Intro #

This manual guides you through importing ASCII files into Geolantis.360 quickly and correctly.
It covers how to prepare your file, map data fields, and complete the import process.
Whether you’re new to ASCII or just need a refresher, this guide keeps it simple and practical.

You can import both CSV and TXT files into Geolantis.360.
A CSV uses commas, while a TXT can use tabs or semicolons to separate data.
Both are plain text formats and easy to edit in Notepad or Excel.

Preparing Your ASCII File for Import #

Before importing your ASCII file into Geolantis.360, make sure it follows these formatting rules:

1. Header Row
   The first row of your file must contain the column headers.
2. Separator
   Use a consistent separator throughout the file:
   • Tab
   • Semicolon (;)
   • Comma (,)
3. Decimal Format
   • Decimal numbers must use a point (.) as the decimal symbol.
   • Example: 52.123456
   • Avoid using commas for decimals: 52,123456
4. Column Order
   The order of columns does not matter.
   • During import, you will manually assign each column to its corresponding field (e.g., X, Y, Z, Identifier, Grouping, Attributes).

Instructions #

1. Open the Import Window
   • Navigate to “Import Geo-data” in Geolantis.360.
   • At the bottom of the window, you’ll see the supported formats listed.
2. Upload Your ASCII File
   • Drag and drop your ASCII file into the window, or
   • Click the file area to open the Windows file selector.
3. Choose or Create a Project
   • Select an existing project to import the data into.
   • If no project is selected, a new project will be created using the file name.
4. Choose a Category (Optional)
   • Select an existing category to assign points to a feature class.
   • If not selected:
     • The feature class will be named after the file.
     • You can also assign it later from a column in the file.
5. Set the Projection (EPSG Code)
   • Choose the correct EPSG code matching your surveying setup.
   • Note: Data collection is done in WGS84
     • Most imported data is in Cartesian coordinates.
     • These are transformed back to WGS84 using the selected projection.
6. Map File Columns to Fields
   Assign columns from your file to the appropriate fields:
   • Z Value: If no height data is available, set Z to 0.
   • Identifier: Defines the name of each point.
   • Grouping: Defines the feature class.
     • If the class doesn’t exist, it will be created automatically.
   • Attributes: Select columns to add as attributes.
     • If a category was chosen, you’ll be prompted to assign attributes.
     • You can also create a select list from column values.
7. Press “Import”
   Once everything is set, click Import to begin.
8. Done!
   All points from your ASCII file are now imported into Geolantis.360.
