Hi all,
I am currently working on a GIS monitoring application that has to provide 2D view(s) of a dynamic geographic dataset (here a communication network with its nodes and links, but also moving vehicles). I belive GeoTools has a lot to offer here. The network is not supposed to move, but the nodes' attributes will change over the time and we want to render it accordingly, using SLD rules. The point here is that most of our data is vector data (except a background satellite image) and the complete dataset is not very big, say maximum 500,000 features in total, but each feature can potentially be updated (at least one attribute per feature, maybe more), say every 5s. In addition, there will be a few static features, most likely coming from shapefiles. Since GIS dataset are usually way bigger and more static, I wonder if the streaming renderer is suited for this dynamic usage. If not what would you suggest? Again, if not, how difficult would it be to adapt one of the existing renderers to ensure a good performance with higher refresh rates and many changes? We are actually considering using a memory datastore. Then my second question is: is the MemoryDatastore a good option? Or should we implement our own memory datastore? Extending the existing MemoryDatastore? Any suggestions are very welcome. Thank you. Olivier PS: It is the 3rd time I am sending this to the list. The 2 first were with a Gmail adress. Do we still have filtering issues with the Gmail users? ------------------------------------------------------------------------- Using Tomcat but need to do more?
