The conversion process from data in the shapefile format to data in the GML format can be divided into two major steps: one is to obtain data based on the data in the shapefile data documentation, and the other is to construct the data in the GML format according to the GML standard. From the analysis of the shapefile data format and the GML format, we can see th

The system is dead, and the data is live. In some areas involving sensitive data, you may need to provide the client data access function. For example, a company has a WebGIS System Based on ArcGIS Silverlight API, which provides some common business functions to access some basic geographic data and basic business data. Some business data, due to confidentiality requirements, may not be directly provided by the system and needs to be accessed directly from the client. Accessing

Shapefiles are the most common format for GIS vector data, and just about every GIS program, free or other cial, can open them. unfortunately, older vector data is often in the ArcInfo interchange e00 format which, unlike shapefiles, isn' t a well-known ented format. export free GIS programs can't open e00 files at all, and even those few that can often have problems handling them correctly. but there's a fairly simple two-stage process that can accurately convert vector e00 files into

ESRI shapefile(SHP) is an open space data format developed by ESRI. Currently, this file format has become an open standard in the geographic information software field, indicating the importance of ESRI in the global geographic information system market. I read some documents and was interested in one sentence. "The shapefile file does not contain the topological data structure" [Several other pro

1. the SDE element is exported to the shapefile. 1. Create a New shapefile. private bool CreateShapefile(string filepath, string name) { bool isSuccssed = false; try { IFeatureWorkspace pFWS = null; IWorkspaceFactory pWSF = new ShapefileWorkspaceFactoryClass(); pFWS = pWSF.OpenFromFile(filepath, 0) as IFeatureWorkspace;

the feature name used by the data source, usually the Shapefile file name and the Shapefile type name are usually the same. store = (simplefeaturestore) datastore.getfeaturesource (featurename); Associate default transaction and data source Store.settransaction (transaction); Create filter FilterFactory2 FF = (FilterFactory2) commonfactoryfinder.getfilterfactory2 (null);

Recently, we have processed road links nationwide and want to create a complete Path Based on Link names, levels, and attributes. To ensure efficiency, the shapefile format is used as the intermediate format and gdal is directly used to manipulate the shapefile format. Data export and link belong to the same judgment, linestring flip, linestring link, data export, and other modules have been compiled. Fi

Main Content Overview1. Parse the Shapefile (. shp) file. ‘2. Projection of latitude and longitude data according to Mercator (call Proj.4 Library).3. Draw the data in OpenGL mode.The above 3 aspects are only to complete the preliminary drawing, there is a big gap for the completion of a complex geographic information system,Here's a simple geo-information framework I designed (for communication, progress). First, it's easier to understand the diagram

ArcGIS files are divided into three types: shapefile, coverage, and Geodatabase.For example, if you use the TXT and DOC file formats that have been used for a long time, you have not checked their differences and relationships, you don't need to worry too much about learning so many data formats in ArcGIS. You just need to know some of their basic applications: Shapefile: A file format that stores GIS data

Gdal Introduction GDAL (Geospatial Data Abstraction Library) is an open source raster space Data Transformation database under the X/mit license agreement. It uses an abstract data model to express the various file formats that are supported. It also has a series of command-line tools for data conversion and processing. Gdal official website: http://www.gdal.org/, it can support the current popular map data format, including grid and vector map, specific reference to the official website. The
