Shapefile Explorer is a simple open source utility to let you explore shape file (.shp) and their complements .dbf and .shx files.
Press the open button to choose your shape file and its accompanying dbf and shx files. Note that the app sandboxing require you to select the 3 files from the open dialog, otherwise the app won’t have permission to open all the files. If you select one file only it will attempt to display what it can, but you can press the open button again and open the missing files. If your files are in the downloads folder you can select only one file as the app has full permission on that folder only. The app will show at the bottom of the screen which files it still requires if any.
Once opened, it will show the information for each shape included in the dbf file in a table. You can search it as well.
When you tap on a line, it will display the corresponding shape on the map in the bottom part of the screen. Currently only polygons are supported.
