My name is Ramona and I'm from Romania. I'm new to GIS. I want to digitize a topographic map in ArcGIS 9.3 and cannot. I tried these steps: I created a Personal geodatabase inside a raster dataset, then I loaded a tiff (mosaic) and a Personal geodatabase feature dataset (with more Personal geodatabase feature classes). However, when I start to edit, the software puts the last vertex. I'm using Windows 7 Professional.
There may be the problem with the spatial reference of your raster dataset and your feature class. Try to look for them probably it might help you.
