Hi everyone, I am starting a new project based on GeoTools and I would be very happy to have your advices on where to start. I have started to read the user manual, but it is really HUGE and I don't really know where to start.
To make it simple, I have a file containing different geographical informations (cost lines, iso-levels, etc., all in one file) that I would like to draw in a Swing component. This file comes in two formats : an ASCII format issued by another code (which is not standard but lists the points coordinates) or a NetCDF format. My first reflex would be to extract data from the file, store it into a data model that I could pass to the renderer... But in GeoTools, I get very confused with the naming of everything. If I got it right, I guess my cost lines are features of a cost line feature type, iso- levels are features of an iso-level feature type, and so on... Here are my questions : 1) Swing component : I know there is a JMapPane available, but it is apparently not adviced to use it... Is there any alternative ? What would you do ? 2) NetCDF : there is a NetCDF reader here http://javadoc.geotools.fr/2.5-M3/org/geotools/image/io/netcdf/package-summary.html that doesn't seem to be present in the final release. Should I implement my own reader or is this one mature enough ? 3) I have seen code were the geographical information is read from file, passed in java objects and then loaded in a MemoryDataStore. The performance is very poor. Should I create my own DataStore (I have read the tutorial about creating a DataStore, but I am not sure it is relevant) 4) I still have some problems with the concept of the DataStore. Is a datastore the data model ? Should I have more than one ? I want to display different data, with different colors, coming (one day) from different files, should I create one datastore for each type of data, for each file ?
