Hi,
I am doing a project where I am digitizing a map of Haiti from the 70s. Through R2V I digitized the lines and then I exported it into ArcGIS 10. I am just interested in the land use change, therefore, I have deleted the other vectors. I want all of the land use change areas to be complete polygons. I performed through data management in the toolbox a feature class to polygon operation. This was somewhat successful as you can see from the blue polygons in the attached image. However, it did not identify all polygons. When I have complicated and nested polygons how do I get ArcGIS 10 to identify them as such? Your help would be much appreciated!

I would suggest running the Check and Repair Geometry as an option on the polyline feature class. Once you have ran these two tools against the feature class, then you can run the Feature To Polygon tool. This should give you a better resulting polygon feature class representing your Land Use. If you are up to date with your maintenance, please submit a webform with us in Support Services if issues still occur. Gracias, Megan!
