I found an answer right away at mapserver. Cartographical Symbol Construction with MapServerĀ¶ http://mapserver.org/mapfile/symbology/construction.html Other ideas are very much appreciated!

The ArcGIS documentation actually has pages titled "What is a feature service" and "What is a map service", the text of which is quoted verbatim here -- Feature Service: Feature services allow you to serve features over the Internet and provide the symbology to use when displaying the features. Clients can execute queries to get features and perform ...

A feature server serves individual layers (aka features) as structured text (xml or json) a mapserver serves maps as images (png - jpeg - gif)

Rather than formatting text for WKT, you should directly use the numeric coordinate data since it is faster and lossless: update t1 set the_geom = ST_MakePoint(t1.xcoordinate, t1.ycoordinate); And if you also need to assign an SRID: update t1 set the_geom = ST_SetSRID(ST_MakePoint(t1.xcoordinate, t1.ycoordinate), 4326);

I figured it out, It should be like this: update t1 set the_geom=st_geomfromtext('POINT('||t1.xcoordinate||' '||t1.ycoordinate||' )'); It worked fine!!

There are many solutions for your question, some more suitable than others based on constraints such space/memory available in your servers. The client side looks like simple because you do not want to overlay any other layer at this moment, so leaflet or openlayers can help you. The server side is a bit trick, since you need to decide how to provide your ...

Another option you could explore is using Tilemill to generate tiles from your GeoTIFFs. You can then just put the tiles on a webserver and call them using Leaflet. No need to set up databases or middleware. Basically you load the GeoTIFFs into TileMill and export it as MBTiles. This is MapBox's format for storing the tiles in a SQLite database. You then ...
