Aspose.GIS for .NET

Aspose.GIS for .NET


Aspose.GIS for .NET enables you to access & manipulate geographic information from vector-based geospatial data formats. API supports to read, write & convert most popular GIS file formats such as Shapefile, GeoJSON, FIleGDB, KML & OSM XML as well as render a map from supported formats to SVG.  Furthermore, a developer can easily customize rendering and feature styles to get the desired map look. 

Aspose.GIS for .NET is designed with simplicity, performance, usability & portability in mind. It contains APIs to be used with .NET Framework, .NET Core & Xamarin platforms, enabling you to build cross-platform applications with great ease.


Advanced .NET GIS Formats Manipulation API Features

Inter-convert Geo Formats

Aspose.GIS for .NET provides the capability to convert Geo file formats with just one line of code.

Convert ESRI Shapefile to GeoJSON - C#

// load & convert Shapefile     
VectorLayer.Convert(dir + "template.shp", Drivers.Shapefile, dir + "output.json", Drivers.GeoJson);

Read or Create GIS Data Files

Aspose.GIS for .NET not only supports loading GIS file formats for manipulation & conversion but it also provides the capability to create GIS data files from scratch. .NET developers can use the API to create basic geometries such as Point, MultiPoint, Line, MultiLine, Polygon and so on, which can be further used to generate complex features.

Format-Independent Object Model

Aspose.GIS for .NET lets you manage geometries and feature attributes of supported GIS file formats without worrying about the underlying format implementation. The uniform representation of feature attributes for both ESRI Shapefiles and GeoJSON frees you from writing separate code to manage both formats.

Support for Spatial Reference System

Aspose.GIS for .NET supports Spatial Reference System. .NET GIS API allows you to create spatial reference system from Well-known Text (WKT) as well as provides the ability to export the spatial reference system to WKT. Furthermore, you may also compare spatial reference systems or create one with custom parameters as per application requirements.
