Hi, >> can you plz help me out in openjump.. >> >> i am new to openjump .. i got a project to customize it according to needs.. >> the needs are .. >> >> 1) they required a software which will perform all topological cheaks >> eg, undershoot of lines , overshoot of lines .. self intersection of line >> strings .. and several others .. >> I think OpenJUMP is well suited for this kind of task and it has already nice features.. but you'll probably have to develop some features by yourself. First of all, OpenJUMP uses JTS library which is excellent to do geometry analysis. Secondly, there is already a validation plugin (Tools>QA>Validate layer) which can accomplish several checks (ex. detect self intersecting linestrings which are "non simple" linestrings in OGC jargon). Undershoot and overshoot do not exist (as far as I know), but it would be interesting to add (you need to have a good understanding of JTS and OpenJUMP API first, but you'll find help on this forum) There is a qa extension available on the website, which is a part of jcs conflation suite. I internationalized these plugins and upgraded them for OpenJUMP 1.2. It has some useful components for data quality controls. >> 2) road network connectivity cheack .. >> I developped several plugins to do this kind of control for my work. It is not yet released (mainly because it is not internationalized) but it could be. I used JGraphT library to perform graph analyses and developped only a few classes to wrap OpenJUMP geometries into JGraphT library (I can give you this glue-code so that graph analysis always use the same codebase). >> 3) integrity check of data .. (at various levels) >> Mainly depends on what kind of check you need. You'll probably have to develop what you need by yourself.
