Open the Mac App Store to buy and download apps.
SHP Viewer is a simple shapefile viewer. The Esri Shapefile or simply a shapefile is a popular geospatial vector data format for geographic information systems (GIS). A shapefile is a digital vector storage format for storing geometric location and associated attribute information. This format lacks the capacity to store topological information.
I bought this because I had a grad school presentation due in a couple of hours and a map I needed only seemed available as a zipped shp file.
This app did not open the file--okay, it DID technically open it, but all of the detail was gone. It was supposed to be a map delineating areas and all I could see were globs of color in an approximate map shape. The thumbnail on the website showed much more detail. So disappointing as I will likely never use this app again as it clearly performs poorly at its one task.
Later (after much frantic searching), I found a version of the map that someone had converted to other formats and was able to get the presentation done on time. Next time, do a bit more research--there ARE free shp viewers out there, and there's no way they can be worse than this one.
simple viewer and not much else
this app can simplly view .shp files, and thats about it. There is an opption to add additional .shp files in the same window, but there is no way to edit individual layers within files. All lines for each .shp file are treated as if within the same layer and the line color, fill color, and background color are editable and you can apply oppacity as well. No export or save/save as feature, but you can print the file and through the print window and save as .pdf.
Good for having something to open SHP files with
While SHP files now open in something for me when I click on them, it leaves some things to be desired. I wish it used the pinch-to-zoom API that Preview uses, for example. And what's up with the MobileMe icon being used for the "Add Shapefile" button?
