hello,
I am looking into using geotools for a
fairly simple app consisting mostly of a gridtable and a graphical
representation for the data via a map widget.
My newbie questions for now are:
Would it be a problem (from a
performance or other perspective) if actually use geotools for
plain ol CRUD and not queries of the spatial variety?( i'm thinking
either way the db must be postgis enable right?)
I want to have as a start two layers:
one OSM tiles layer and one point layer. I think i already found the
way to render the feature layer, using the tutorial of course, but i
do not seem to be able to find a way to get the tile layer up and
running. I think i saw a post somewhere that this is not available.
If so, are there any workarounds?...like serving tms as wms or
something?
Do any of the the map widgets (
jMapPane and jMapFrame are the only ones i understand) support the
ability to run spatial queries. To be more precise could i draw a
polygon on the mappanel and the use that polygon to query the db for
features inside that polygon?I'm thinking maybe i could
programatically create a layer to hold the polygon ( or polygons)
and when the user clicks a button i create a query, retrieve the
result and modify the style of those features that are in the result
set ( or actually i could just apply my custom made "feature
selected" style)
Has anyone used hibernate-spatial with
geotools? Would it be redundant?
Thank you in advance for your answers
and your patience
