Testimonials

• "I would like to thank all of the folks at Vivid Solutions, Inc. (VSI) and Refractions Research (RR) for their pioneering work on the JUMP program, and to MSRM for making the project Open Source. I would like to extend our special thanks to Jonathan Aquino for his pristine coding and tireless efforts in answering hundreds of emails that made it so much easier to develop for the JUMP platform, and to Martin Davis for the excellent JUMP architecture. Well done." - Larry Becker
• "WMS work quite well and is it connected quick, compared with other commercial programs" - Dante Fuster
• "Thanks for the JCS 1.1.0 and JUMP 1.2 alpha version, it helped me a great deal futher on my masterthesis :)" - Kristian Lunde
• "now I believe that the power of JUMP + Beanshell is just being tapped. I think I can join you in being very, very excited about JUMP + Beanshell."- Andrew Collins
• "I appreciate a lot the work of OpenJUMP (Jump) community . Thanks to all of you, I can get on more quickly in my research, moreover, using a Open Source GIS. It's fantastic." - Erwan Bocher
• "For the implementation of the Generalisation Services we use an open source framework for mapping application called JUMP that delivers standard functionality for reading and writing files (Shape, GML), as well as modifying and visualising cartographic data. JUMP is written in Java, which allows easy application service provision (ASP) over the internet via Java servlets on a web-server." - Moritz Neun and Dirk Burghardt (cited from a paper of ICA generalisation Workshop 2005)
• "Due to the clean architecture of JUMP and programming it is not to difficult to understand the JUMP "flow". Thanks for that :-)" - Ronald Grosmann
• "Patch tested here. Very fast. OpenJUMP each time better." - Ezequias Rodrigues da Rocha
• "As the end of 2005 draws near people look back and my year has been marked by the creation of my diploma work. It has been finished and highly rated due to the help of you members of the [Open]Jump mailing lists." - Axel Orth
• "I am the maintainer of a city guide website. For years we searched for software to allow us to make maps of our town and surrounding areas. Our budget ruled out commercial GIS software. The project remained on the back burner until we discovered Jump. All our problems were solved overnight!" - Joe Desbonnet, Galway.Net
• "It is already my favorite program, thanks to its free code and its powerful topology library." - Michael Michaud
• "The last time I got an excellent snippet of help from Jon when I was creating a standalone gis application for gps tracking of a fleet of ground based vehicles. The project was a success ... JUMP is a very strong contender as a gis development platform." - Luke Lincoln
• "I work for the municipality of Cremona Italy. We consider JUMP very interesting for our gis." - Adamo Bozzetti
• "JUMP works really nice on Linux!" - Anse
• "I am a volunteer working in GIS in Jamaica. So far, I have tested many GIS to find the best friendly-user Tool to use in here (budget constraint). I think OpenJUMP, so far, is the best. I tried QGIS, gvSIG, uDIG, TatukGIS (Free Viewer) and ESRI ArcExplorer (Free Viewer)." - Nicholas Gignac
• "All in all I'm quite happy with OpenJUMP!!! It's simple enough (from a developer point of view) to be grasped in a reasonable amount of time, yet it's powerful enough to implement quite easily many different things." - Paolo
• "Currently I'm working (read only) on a map with some 16 layers from PostGIS having a total of some 100.000 linestrings, 188.000 points and 40.000 multipolygons and it's stays inside 256 MB of "Committed Memory" as JUMP reports it!!! Even if it sometimes goes "Out of Memory" it usually recover, and after a run of the garbage collector it goes down to some 145 MB (it depends on the zoom level). If you add some "Datastore Query", memory consumption may be higher, because the query is run once and results are stored in memory, the same applies with Shape files. But if you use only (or mainly) tables from PostGIS, you should have no memory problems. All in all I'm quite happy with JUMP/OpenJUMP, it's the first open source GIS client that really works with "my" data." Bye - Paolo Rizzi
• "Our reasons for this choice [choosing JTS] was easy distribution of results, better control of algorithms and relative easy transmition of old algorithms from ESRI AVENUE environment. Another advantage was possibility to test processing algorithms based on JTS in visual JUMP environment." - Karel (in a paper of the ICA Generalisation Workshop 2006)
