I have polygons that has huge number of points. One of the polygon was
over 300,000 points originally. It is still huge after we smoothed it.
In v2, I uses FromEncoded(). The performance is bad but at least it
shows on the map. I understand that the polygon drawing is improved in
v3. But with some many points, I don't feel it will do too much.
I think the best solution is to use tiles. Even there are lots of
tiles at deep levels. But most will be blank. Following is what's in
my mind.
Create database table with key on (zoom, x, y) and an image column
store the images (or a reference to a image file).
for each tile in my country (zoom, x, y) // how to get the coords?
{
for each (polygon that intersects the tile)
draw the polygon on the tile.
save the tile and remember it is database.
}
When request for (zoom, x, y), I simply search the database, return
the image if finds one.
The idea is simple and I believe it can be done. My questions are:
Is there any service/tool that can do what I described. I see tile
cutting tools but all take an image as input which will lost details
when doom in.Also, I don't want all those blank images.
