Touch GIS allows you to import georeferenced raster imagery. You can also import non-georeferenced imagery and manually place it on the map. Raster imagery can be managed in the Layer's panel.
Touch GIS supports importing the following raster formats:
- World File
Note: Imported rasters are automatically tiled to improve performance.
Touch GIS allows you to place non-georeferenced rasters on your map by selecting a series of correlated visual reference points. Here's how:
- 1.At the bottom of the Layers panel select 'Import'
- 2.Choose the file you want to place (typically a TIFF, PNG, or JPEG)
- 3.After importing, you'll be prompted to select your first reference point. Pan and zoom to select a visual point that you will be able to correlate with a feature on the basemap. Select Next.
- 4.Next you will select the corresponding reference on your basemap. Pan and zoom to find this spot.
- 5.You will need to repeat this process two more times for a total of 3 reference points to place your raster image.
After all 3 points have been set you can edit their position if necessary from the Layers panel.
