Does anyone know of a library in Java that can parse ESRI Shapefiles?

I'm interested in writing a visualization program for the road data in the 2009 Tiger/Line Shapefiles . I'd like to draw the line data to display all the roads for my county. The ESRI Shapefile or simply a shapefile is a popular geospatial vector data format for geographic information systems software. It is developed and regulated by ESRI as a (mostly) open specification for data interoperability among ESRI and other software products. 1 A "shapefile" commonly refers to a collection of files with ".shp", ".shx", ".dbf", and other extensions on a common prefix name (e.g., "lakes.*").

Does anyone know of a way, in Java, to convert an earth surface position from lat, lon to UTM (say in WGS84)? I'm currently looking at Geotools but unfortunately the solution is not obvious. No Library, No Nothing. Copy This! Using These Two Classes , You can Convert Degree(latitude/longitude) to UTM and Vice Versa! private class Deg2UTM { double Easting; double Northing; int Zone; char Letter; private Deg2UTM(double Lat,double Lon) { Zone= (int) Math.floor(Lon/6+31); if (Lat<-72) Letter='C'; else if (Lat<-64) Letter='D'; else if (Lat<-56) Letter='E'; else if (Lat<-48) Letter='F'; else if (Lat

how to convert between degrees, minutes, seconds to Decimal coordinates

问题 Looking for a java utility. It is even better if you can tell me how to do it using geotools library. 回答1: By "Decimal coordinates" do you mean latitude and longitude (also known as the decimal degree)? If so, what you're trying to do is pretty easy: Given a DMS (Degrees, Minutes, Seconds) coordinate such as W87°43′41″, it's trivial to convert it to a number of decimal degrees using the following method: Calculate the total number of seconds, 43′41″ = (43*60 + 41) = 2621 seconds. The

geotools修改shapefile 属性名乱码问题

在GeoServer中文社区的讨论地址为:http://opengeo.cn/bbs/read.php?tid=1701&page=e&#a 使用geotools修改shapefile之后, 发现dbf文件内容中, 属性名都成了乱码, 但属性值就不是乱码。修改之前还没有乱码的。 而且在代码中也已经通过以下方式设置过编码方式了: ShapefileDataStore shape = new ShapefileDataStore(url);shape.setStringCharset(Charset.forName("GBK")); 我的修改代码如下： /** * 修改shapefile. * @param dataStore * @param fidStr 要修改的数据对应的featureID * @return */ public static boolean updateShapeFile(ShapefileDataStore dataStore,String fidStr) { DefaultTransaction transaction = null; SimpleFeatureStore store = null; try { dataStore.setStringCharset(Charset.forName("GBK")); String[] featureNames
