I think this is a great question and one with more relevance as we start using different technologies to store spatial data such as PostGIS. There are two issues involved here, from what I can think about: 1) Scale: I used to teach cartography students that a City from the view of "The Country" is a point, but as you zoom in to the scale of a "region", ...
Degrees are part of a modified Sexagesimal (base 60) number system. Even though there are 360 degrees in a circle, 360 is 6 x 60. The origin of degrees as angular units is unclear (see wiki/Degree_(angle)#History.) See Coordinate Conversion: Decimal Degree to Deg-Min-Sec of lat/long Coordinates for subdivisions of a degree. In terms of fundamental ...
I am using vector and raster approach to solve it. The script below has 3 input parameters: a) polygons (must be single part), b)output point feature class to store the points most distant from polygon boundary c) tolerance in map units. Algorithm: POLYGON =shape geometry calculate centroid of POLYGON (p1) Define distance from centre to polygon outline ...
If i got you, you want to check if your circle can be inscribed inside the polygons.You can do it in ETGEOWIZARD,an arcmap addin, (see pics below) for those polygon and separate those maximum inscribed circles have area greater than or equal to that of your supplied circle-you can use select by attribute to separate those circles(>= your sample circle ...
Take a look at this fiddle. I've made some modifications, basically I remove the highlight interaction (on removefeature) and put it back on pointermove event.
The following program ArcMap2SLDConverter will generate an SLD file from an ArcGIS Map - but you must have ArcGIS installed and running to do so. This SLD can then be uploaded to GeoServer, and used to style the corresponding layer.
The solution is that in my code I had called in "loadFeatures" twice, once in each of the layers. Simply by renaming one of them it stopped calling both layers into the single one.
You can use the Integrate tool to insert a vertex at the intersection the two lines. Just make sure your contour dataset has a lower rank and your blue line datasets is Z aware. The Integrate tool does not honour the Z value (I checked this on some sample data) so you would then need to update the Z property of the inserted vertex. Now at this point I'm ...
