Spatial Data management¶

The data management is made through the Data menu, it contains the following elements:

Link data... (Ctrl+O): reference a support layer which will be displayed in your project

Unlink data... (Ctrl+W): unlink a layer

Import data: import data into one of your construction theme

Link data¶

The Data ‣ Link Data... option allows loading some support themes for the vectorization of the construction layers. Those support themes can be vector data (*.shp) or raster data (*.tif, *.JPG and Esri’s binary GRID).

In the opposite of the construction layers, the support themes are not stocked in the project but only referenced.

Rotation¶

Some of your files may have rotation information, which is not yet supported by ToolMap. In that case you will see the following message:

rotation information
display option

This message will pop up every time you make an action regarding the layer (including trivial actions like zoom or pan), so be sure to convert your images into non-rotated rasters (see Rotation Warning). If the rotation is insignificant, you may prefer to simply ignore the message by checking the option Hide warnings for this layer. This option prevent the appearance of the message for the current session, but it will pop again the next time you launch your project.

Import data¶

The Data ‣ Import data... option allows you to import some existing information into your construction layers. You can only import lines or points geometries. The process is made in 3 different steps.

Step1¶

the File type option allows two types of data, choose the one you want to import
Go to the next step of the import or cancel the operation

Step2¶

If you choose to add a shapefile the following step comes ahead

Directory path of the shapefile
data information of the shapefile
allow to go back to Step1 or to continue to Step 3

If you choose to add a CSV file the following step comes ahead

Directory path of the CSV file
Information on the CSV file
allow to go back or to continue to step 2.2

Step2.2¶

The CSV files are composed of columns of data separated with commas, you will have to choose wich column you want to assign to the X and Y coordinates

List of the columns which can be assigned as X or Y coordinates
allows to go back or to continue to Step3

Step3¶

List of layers within the data will be imported (with the shapefile import the choice is restricted to the geometrical type of the data)
import the data or cancel the operation
