How are GIS fields added to a layer?
To add GIS fields or attributes to a layer in tcpGPS, you must follow these steps within the layer management menu:
Access attribute editing: In the layer manager, SELECT the desired working layer (Point, Line, Polygon) and press the Edit button. This will automatically open the GIS attribute editing menu.
Add new fields: Within this menu, use the Add (+) button to create new attributes that will belong to all elements (points, lines, or polygons) associated with that layer.
Configure the data type: For each field, you can choose from the following available types:
Integer: For numbers without decimals.
Real: For numbers with decimal format.
Text: For any character string.
Date: Opens a calendar to select the day in dd/mm/yyyy format.
Image: Allows associating photographs taken at the point (they are linked as JPEG files when exporting to SHAPE).
List: Displays a preconfigured template to quickly select options without typing.
Save the structure: Once the fields are defined, press the Accept/Save button to confirm the changes to the layer structure.
Important considerations:
Retroactive modification: If you modify the field structure of a layer that already has measured objects, the information of those objects will automatically Adjust to the new edited structure.
GIS templates: You can use the templates button to speed up the process if you frequently use the same types of fields in different projects.
Field use: After configuring the fields, you can enter their values (Key:Value format) during the Survey or later in the point editing screen.
Export: All this information is saved in the Drawing Data database and can be exported along with the geometry in Shapefile format, compatible with programs like QGIS.
