THE GEOBASE EDITOR
GENERAL
A GeoBase is a text file ( ASCII ) containing survey information, coding and point coordinates in a format specific to COVADIS . Although this file can be read and modified by any text editor, a special editor ( the GeoBases editor ) has been developed. This chapter proposes to introduce you to the functionalities specific to the GeoBase editor.
Each of the topometric calculations modifies the current GeoBase (coordinates of calculated stations, V0 of stations, coordinates of detail points, etc.).
Each line of a GeoBase defines a particular element ( station , reference , measurement , point , comment , …) and is composed of a line number, the type of the element described, and the parameters associated with this element. The symbol column is only used to fill in the code attribute of the topographic points and plays no role when generating the drawing ( coding ).
To launch the GeoBase editor, select the “ Edit GeoBase ” option from the Cov.Calculations menu or type GEOEDIT2 on the AutoCAD command line . The last GeoBase used ( book file reading or calculation ) can be loaded automatically when starting the editor.
An example of the GeoBases editor window is given below :
The name of the current GeoBase ( currently loaded ) is always displayed in the title bar of the window, the "*" character indicates, if present after the name, that the GeoBase has been modified since the last save ( or since loading ).
The GeoBases editor can be broken down into three main areas: the menu bar , the toolbar and the display list .
These different areas are described later in this chapter. It is possible to customize the size and location of the editor window, the display font of the list, the number of decimal places displayed as well as the width of the columns of the list. Different colors can be chosen for each column or each type of row.
REMARK : | |
➪ | The various messages generated by the GeoBase editor are sent in the AutoCAD text window (error during loading, element modifications, calculation results, etc.). |
➪ | A line in the GeoBase generally corresponds to a line in the display list in the GeoBase editor. This is not true for traverses with more than eight stations which are the subject of several lines in the GeoBase file. |
➪ | All calculations can be performed either in the GeoBases editor or from the Cov.Calculations menu . |
THE MENU BAR
The file menu
This menu is used for GeoBase management : creation, opening, saving, concatenation and writing of listing files. The different menu options are described above .
₪ “ New ” : allows you to create a new empty GeoBase named GeoBase.geo. If the current GeoBase has not been saved, the program asks if it should be saved before creating the new GeoBase. If you choose “ Cancel ”, the new GeoBase will not be created.
₪ “ Open… ” : Allows you to load an existing GeoBase. If the current GeoBase is not saved, the program asks you whether to save it before choosing the GeoBase to open . The choice of file to open is made using the file selection dialog box.
₪ “ Save ” : saves the modifications made in the current GeoBase. A calculation option allows saving the GeoBase before modifications with a 'gbk' extension .
₪ “ Save as… ” : Allows you to save the current GeoBase under another name or to another location on disk.
₪ “ Save display as… ” : Allows you to create a GeoBase containing only the visible elements of the list. The name of this GeoBase is requested via a file selection box. This GeoBase becomes the current GeoBase. This command allows, among other things, to extract the network of polygons keeping only the points, the stations and the references.
₪ “ Concatenate… ” : Allows you to add another GeoBase selected via the file selection dialog box to the end of the current GeoBase. This command allows, among other things, to complete a GeoBase with a complementary survey.
Caution: the projections attached to the two GeoBases must be the same. Otherwise, an error message appears and cancels the operation. It is then necessary to standardize the projections of the two GeoBases.
₪ “ Print GeoBase… ”: Opens the current GeoBase in the editor defined in the listings configuration for text files in listing mode. If necessary, the program asks for confirmation for the registration of the GeoBase.
This command allows, among other things, to make modifications to the GeoBase file itself. These modifications assume a perfect knowledge of the GeoBase recording format. It is then necessary to reload the GeoBase in the GeoBase editor to take into account the modifications made outside the editor.
₪ “ Print listing… ” : Creates a file on disk allowing you to print the current GeoBase as it is displayed in the GeoBase editor (unsaved modifications included). Only the elements displayed in the list will be present in the listing file. The editor used to view this listing is the one defined in the configuration of listings for files in Word format . The name of the listing file is that of the GeoBase.
The edit menu
This menu offers functions for modifying, deleting and adding new elements to the current GeoBase.
₪ “ Cancel ” : allows you to cancel the last action performed.
₪ “ Redo ” : allows you to redo the last undone action.
₪ “ Edit… ” : Allows you to edit the item selected in the display list. This menu option is only active if a single item is selected.
₪ " Delete " : allows you to delete all the elements selected in the display list. The deletion will only be effective after confirmation.
₪ “ Add… ” : Allows you to add a new element at the end of the GeoBase. The selection of the type of element to create is done using a dialog box.
₪ “ Insert before… ” : Allows you to add a new element before the element selected in the display list. This menu option is only active if a single item is selected. The choice of the type of element to create is done using a dialog box.
₪ “ Insert after… ” : Allows you to add a new element after the element selected in the display list. This menu option is only active if a single item is selected. The choice of the type of element to create is done using a dialog box.
₪ “ Change HP… ” : Allows you to modify the prism height of a set of selected observations. You have the possibility to add a constant to all the selected observations or to give a new value.
₪ “ Change Prism Constant… ” : Allows you to modify the value of the prism constant of the selected observations.
₪ “ Change altitude… ” : Allows you to modify the altitude of a set of selected points. You have the option to add a constant to all elevations or give a new value.
₪ " Change symbol " : allows you to change the symbol code for all the selected elements.
₪ “ Set X and Y to 0.0 ” : allows you to zero the planimetric coordinates of a set of selected points.
₪ “ Set Z to 0.0 ” : allows you to set the altitude of a set of selected points to zero.
₪ " Delete V0 " : allows you to delete the V0 attached to the stations appearing in the selection.
₪ “ Delete HP, AV and DI ” : allows you to delete the instrument height, the vertical angle and the slope distance from the selected measurements and references.
₪ " Delete Z " : allows to delete the altitude of the points of the selection.
₪ " Delete XY " : allows you to delete the planimetric coordinates of the points of the selection.
₪ “ Make X and Y constant ” : makes the planimetric coordinates of the selected points invariant. This command saves you from modifying the points one by one.
₪ “ Make Z constant ” : makes the altitude of the selected points invariant.
₪ “ Make X and Y variable ” : allows you to make the planimetric coordinates of the selected points variable. This command saves you from modifying the points one by one.
₪ " Make Z variable " : allows you to make the altitude of the selected points variable.
The context menu
In the GeoBase editor window, a right click with the mouse displays the contextual menu above.
The commands available in this menu depend on the items selected.
₪ “ Edit… ” : Same as a double click on an item.
₪ “ Delete ” : allows you to delete the selected elements.
₪ “ ⇢ Reference ” : transforms the selected measurements into references.
₪ “ ⇢ Measure ” : transforms the selected references into measures.
₪ “ ⇢ Circle to the right ” : transforms an observation made in a circle to the left ( Av > 200 gon ) into an observation in a circle to the right.
₪ “ ⇢ AV Reading ” : transforms rear staff readings into front staff readings.
₪ “ ⇢ AR reading ” : transforms front rod readings into rear rod readings.
₪ “ ⇢ Reverse. Path. » : Inverts the definition of the paths (order of the stations)
₪ “ ⇢ Comment ” : turns selected items into comments. This command allows you to "freeze" the selected elements so that they are no longer taken into account in the calculations. Traverse definitions cannot be commented out.
₪ “ Comment ⇢ ”: Attempts to transform the selected comments into meaningful elements.
₪ “ Add… ”: Request to select a type of element to add at the end of the GeoBase.
₪ “ Insert before… ” : Inserts an element before the selected line.
₪ “ Insert after… ” : Inserts an element after the selected line.
₪ “ Search… ” : Opens the dialog box for searching for an element (by its personnel number). If only one line is selected, takes over the personnel number of this line and launches the search on this personnel number.
₪ “ Attributes… ”: Some coding commands may contain attributes. These are information in text or photo form that do not affect the behavior of the encoding command. These attributes are entered at survey time and appear in the window above.
The attributes and their value are listed at the top.
The preview contains the first photo attribute.
The button launches the Microsoft Paint software in order to be able to print the photo. It is necessary to select the photo attribute to have access to this button .
The display menu
This menu allows you to activate and deactivate the display of the different types of elements in the list.
For the elements of a given type to be visible in the display list, it suffices that the corresponding option in the menu is checked (symbol ✓ in front of the text of the option).
Example :
The measurement lines will not be displayed in the list. 
The measurement lines will be displayed in the list
₪ " Display all " : allows you to display all the elements of the GeoBase
₪ “ Select… ” : Opens a dialog box allowing you to select, in a single operation, the elements to display and those to hide.
₪ “ Element icons ” : allows the icon representing them to appear in front of the elements in the list. This makes it possible to differentiate the types of elements much more quickly.
₪ “ Prism constant ” : displays the column reserved for prism constants used to measure distances.
₪ " Update symbol column " : You can check this option to update the symbol column of the elements when you make modifications. This operation requiring a lot of time, it is advisable to deactivate it.
₪ “ Text window ” : displays the AutoCAD text window in which the various messages generated by the GeoBase editor are sent are sent in the AutoCAD text window (error during loading, element modifications, calculation results…).
REMARK :
☛ These options are very interesting for quickly finding the elements to modify, as well as for limiting the creation of a listing file to the desired information ( stations + references , for example) or extracting a network of polygonals with the command " Save Display as... » From the File menu .
☛ The color and font of the elements present in the GeoBase can be customized for optimal visualization of the displayed content.
The reading menu
This menu is used to convert field notebooks into GeoBase format. For details, refer to Reading Notebook . If the current GeoBase is not empty, a question is asked to complete this GeoBase or to create a new one.
Importing from a database is only available in the GeoBase editor. This function searches the specified database for the coordinates of stations and references according to their personnel numbers, and adds them to the GeoBase.
The export menu
This menu allows you to transform the current GeoBase into another file format. For more details, refer to the Export Carnet . These commands are strictly identical, whether you launch them from the GeoBases editor or from the Cov.Calculations menu in AutoCAD .
Exporting to a database is only available in the GeoBase editor. This function writes the coordinates of stations and references to the specified database.
₪ “ Codification merge ” : opens the dialog box allowing you to merge a code file with the current GeoBase .
The calculations menu
This menu groups together the various classic calculations. Calculations are performed in the GeoBase being edited.
The tools menu
This menu includes GeoBase utilities.
₪ “ Find Personnel Number… ”: This command allows you to select an item from its personnel number. In the dialog box that appears, type the element's serial number and then press the " Search " button . The list of found items is displayed. Select the one you are interested in and press the " Select " button . A double click will have the same effect. This method is recommended for moving quickly through large files. It is also available in the contextual menu of the GeoBases editor. 
₪ “ Find Symbol… ”: This command allows you to select an element containing a certain character string in the symbol column. It is sufficient that the symbol column contains the string sought for the element to appear in the list.
₪ “ Display the polygonation ”: allows a sketch of the sights to appear on the screen before any calculation. The points are calculated step by step. It is therefore necessary to know at least one point whose coordinates will be fixed and an orientation ( V0 or two known points ).
It is possible to display the numbers of the points and the arrows indicating the direction of sightings. A drop-down list contains the point numbers that could not be calculated.
The approximate coordinates of the points are displayed when the mouse cursor passes over them. The mouse wheel is used to zoom (rotation of the wheel) and to move (hold down and slide).
Stations and references are represented with different colors depending on whether they are known or calculated.
The " Finish " button closes the display window and returns to the GeoBase editor. Of course, the approximate coordinates of the points have not been recorded in the GeoBase. The size of the window is identical to that of the GeoBase editor.
₪ “ Auto traverses ”: allows you to search for traverse definitions from sightings . The dialog box above allows you to give a radical to the traverses to be created and to choose the index for the first traverse. It is also possible to delete existing paths.
The principle of this research is to try to create the shortest possible framed paths between two known points. The conditions are identical to those of the visualization of the polygonation (minimum of a known and fixed station in coordinates and known V0 ).
Measurements used in traverse definitions are automatically transformed into references.
₪ “ Re-register… ”: allows you to re-register points and observations.
₪ “ Create all points ”: allows you to create all points with zero coordinates. The symbol attached to the measurement is associated with the point. This command is useful to know if all the radiated points have been calculated.
₪ " Check double points (code)": allows you to delete double points with the same code.
₪ “ Elimination of double points (registration number)”: allows you to delete the double points of registration number.
₪ “ Points sorted at the end ”: allows you to sort all the existing points at the end of the GeoBase. The sorting is done on the personnel number. This operation is not recommended if it is a survey in coded coordinates (GPS…) because it would destroy the order of the survey.
₪ “ Points sorted according to altitude ”: allows you to sort all the existing points according to an increasing altitude. This operation is not recommended if it is a coded GPS survey because it will destroy the order of the survey.
₪ " Precision control (Order 09.16.2003)": performs a control of the survey in application of the Order of September 16, 2003. This order replaces the tolerances of 1980 and 1988.
₪ “ Change of system ”: This new function makes it possible to recalculate the coordinates of the points in a new projection system .
₪ “ Reduction of repetitions ”: It is sometimes impossible to make observations of a station in one go. The survey team therefore returns and performs a recovery. This will result in the GeoBase as two station lines with the same serial number. The reduce command allows you to reduce these two times into one.
You can tick one or more of the options proposed in the dialog above , but the following rules are applied :
☛ | Only the checked options will be taken into account. |
☛ | If you check the first three options, the program gives priority to the first then to the second then to the third |
☛ | You can request to delete stations and their observations that have been reduced. |
☛ | You have the possibility to reduce the observations made in a circle on the left. The average with the observations made in a circle on the right can then be taken. |
☛ | It is also possible to integrate the eccentricities in the observations. |
☛ | Device corrections can be incorporated into observations |
₪ “ Change of Landmark ” :
This transformation performs a plane translation and rotation from two points. The points must be known in coordinates in the two frames. You can choose each of the two points by their serial number, the old coordinates being searched in the GeoBase.
Several options are available :
☑ " All " : You have the choice between processing all the points of the GeoBase or using the list of personnel numbers. If a selection is made before launching the command, the list is automatically filled by the program. Personnel number intervals are written as Ni - Nj and the intervals are separated by a semicolon.
☑ IT is possible to include the invariant points in planimetry ( CP = 1 or CP = 3 ) in the processing by checking the corresponding box.
☑ IT is possible to recalculate the V0 of the stations in the new benchmark. The V0 are corrected by the value of the rotation of the axes. If you need to make path calculations afterwards, it is essential to check this option.
☑ You can project all the points perpendicularly on the vertical plane passing through the new abscissa axis defined by the two chosen points. This option is useful during a facade survey to project the points in the same plane.
☑ It is also possible to assign the Z values to the Y values to work in the general coordinate system without having to create a vertical UCS to view the facade. The Z of the points is not altered.
The transformation parameters are useful information to control the entry of new coordinates. Indeed the distances in the old and the new marker are calculated by the coordinates and a difference between these two values would reveal an error in entering the coordinates.
The set of features in this dialog box makes it easier to work with data from a facade survey. After loading the pattern of points, you obtain a cloud of points laid out according to the plane of the facade in top view ( diagram ① ). You can project these points onto the vertical plane of the facade ( diagram ② ). By inverting the Ys and the Zs , you will obtain points in the XY plane ( diagram ③ ).
REMARK :
You can also insert the pattern with the real coordinates and use the Change reference command of the 2D Cov/Topographic Points menu, which is specialized in facade tilting.
The codification menu
This menu gathers the commands allowing to process the codification aspect of a survey.
This command can be launched from the Cov.Calculations menu or from the GeoBase editor. Its main purpose is to add coding commands, contained in a text file, to the current GeoBase (if the command is launched from the GeoBase editor) or to a GeoBase that you indicate in the specific area.
The text file containing the codes must include on each line :
1) | the number of the surveyed point |
2) | the code separator (the same as that of the table) |
3) | the coding command(s) as they would have been entered in the field. |
₪ " GeoBase " : allows you to indicate the GeoBase to be completed.
₪ « Fichier codes » : permet d’indiquer le fichier texte contenant les codes.
₪ « Table »: permet de choisir la table pour la reconnaissance des codes. Vous pouvez changer de table en utilisant le bouton.
₪ « Faire porter les commandes … »: attribuer les commandes aux mesures ou aux points (coordonnées) de la GéoBase.
Cette commande tente d’ajouter les codes présents dans le fichier de codes aux points (ou mesures) de la GéoBase.
L’ordre dans le fichier de codes doit être le même que celui de la GéoBase ou du levé. Des sauts de points sont possibles (voir le point 102 dans l’exemple suivant).
Exemple de fichier de codes et application sur une GéoBase :
REMARQUE :
L’ordre des points dans la GéoBase et celui dans le fichier texte contenant les codes terrain doivent être identiques.
₪ « Table de géocodification » : ouvre l’éditeur de table de codification.
₪ « Génération du dessin » : ouvre le dialogue de génération du dessin.
REMARQUE :
Cette commande n’est pas disponible dans le logiciel de Calculs Topométriques seul (sans AutoCAD).
₪ « Écriture liste de codes Leica/Trimble »: permet de faire la conversion d’une table de codification Covadis vers une liste de codes exploitable directement sur les appareils Leica / Trimble.
LA BARRE D’OUTILS / CRÉATION D’UN NOUVEL ÉLÉMENT
La barre d’outils est constituée par des boutons permettant d’accélérer l’accès aux commandes principales de l’éditeur de GéoBases.
Il est effectivement plus rapide de cliquer sur un bouton que de dérouler un (ou plusieurs) menu(s).
Sur chaque bouton est dessinée une icône symbolisant la commande associée. Lors du passage de la souris sur une icône, un message (info bulle) est affiché pour rappeler la fonction du bouton.
La création d’un nouvel élément dans la GéoBase courante, le programme lui affecte automatiquement un numéro de ligne en fonction de l’opération souhaitée (ajout ou insertion). Si le numéro de ligne proposé par défaut est modifié, une confirmation sera demandée quant au déplacement du nouvel élément dans la GéoBase.
Un matricule sera aussi affecté automatiquement au nouvel élément si celui-ci n’est ni un Commentaire ni une Commande. Pour ce faire, le programme recherche le dernier élément du même type dans la GéoBase et incrémente l’indice de son matricule.
Pour valider la création d’un nouvel élément dans la GéoBase, il suffit d’appuyer sur le bouton « Ajouter ». Le dialogue restera affiché pour vous permettre d’ajouter d’autres éléments tant que le bouton « Annuler » n’aura pas été actionné.
