First "GIS" tool in AppStore with a very nice GUI and a fast shape- rendering engine. But for basic functions like visulising *.shp and request (only one) selected layer, the app is too expensive. For a real GIS there a to many missed functions - WMS/WFS/GeoRSS integration - Image-overlaying - vectoreditor for own geometries - geoprozessing (buffer, distance, 9IM - between geometries) - posibility to save defined styles - scale - position input via gui - distance/area tool - RGB/Hex-Value input posibility for styles - gradient for self defined attribute intervals - posibility to define different styles for thematic vectors in one shapelayer, so if you want to define different style for a special shape attribute, you have to import the same shp x-Times (x = count of different attribut-values) and set a filter for the attributevalue you want to decorate with a specific style.... But then you have the proplem thats just allowed to request only one layer. so you have to Import the shape again (without any filter) and then set the style to full transparent. So you can request all attributes with the oppertunity to present them in diferent styles Nice Tool for basic GIS functions, but too expensive
