I am working on parsing a MapInfo TAB Format file in Java. It consists of a set of four files viz .TAB, .ID, .MAP and .DAT. After searching on web I came across a parser provided by GeoTools at this repository: https://github.com/geotools/geotools/blob/master/modules/library/main/src/main/java/org/geotools/data/MapInfoFileReader.java When I use this API for parsing the MAPInfo TAB format file bundle, the API throws exception: "Didn't find a minimum of three control points in the .tab file." I am using public MapInfoFileReader(final File tabfile) constructor. I have tried using different

I am need a Java function that will generate a bounding box (rectangle) around a buffer. The buffer is defined by the center point (WGS84 coordinate) and the radius (in meters). Getting a bounding box for a buffer in JTS seems to be quite simple: Point center = .... Geometry boundingBox = center.buffer(...).getEnvelope(); This however is pure planar geometry. Is there a way to do this using a coordinate reference system with the distance given in meters? Optimally with Geotools but other Java solutions will also work... Although you have approached it in another way, I have another solution

I have a number of points which make getOrthodromicDistance method to fail with exception in geotools lib, while these points are valid lat lon points: Point which throws the exception (lat,lon): val p1= (5.318765,-75.786109) val p2= (-6.32907,106.09254) eg exception: No convergence for points 75°47,2'W 06°19,7'S and 106°05,6'E 05°19,1'N. java.lang.ArithmeticException: No convergence for points 75°47,2'W 06°19,7'S and 106°05,6'E 05°19,1'N. at org.geotools.referencing.GeodeticCalculator.computeDirection(GeodeticCalculator.java:1073) Code used in Scala: def latlonDistance(p1:(Double,Double), p2:

So I'm playing with geotools and I thought I'd proxy one of their data-access classes and trace how it was being used in their code. I coded up a dynamic proxy and wrapped a FeatureSource (interface) in it and off it went happily. Then I wanted to look at some of the transitive objects returned by the featureSource as well, since the main thing a FeatureSource does is return a FeatureCollection (FeatureSource is analogous to a sql DataSource and featurecollection to an sql statement). in my invocationhandler I just passed the call through to the underlying object, printing out the target class

We are building a service for uploading zip-files containing an ESRI-shapefile. The service should be able to read the shapefile and do stuff with its content. So I've built a class that unzips the zip-file to temporary folder (subfolder of System.getProperty("java.io.tmpdir")). Another class calls the unzip method from the Unzip-class and it then tries to read the unpacked shapefile using Geotools. It uses the Geotools DataStoreFinder.getDataStore(Map params) method to create a datastore from the unzipped shapefile. Here the problem occurs: the getDataStore-method returns null. I tested the
