https://github.com/panwarnaveen9/View-Module-for-Cartaro-GSOC2014/wiki/Code-Week-%234
*Weekly Report (8th June to 14th June) -*
*Aim* - Design the spatial relationship functions for the module.
*Things, I have done this week*
-
Worked on available code for spatial queries in Cartaro.
-
/supporting_module/postgis/views/postgis_views_handler_filter_geometry.inc
- /supporting_module/postgis/postgis.test
-
Identified and ranked the Spatial functionality which we are going to
provide the Cartaro's user in View module.
-
*Available functions* -
- ST_Contains, ST_Intersects, ST_Disjoint
-
*New relational functionalities* -
1. ST_Covers — Returns 1 (TRUE) if no point in Geometry B is outside
Geometry A.
2. ST_Equals — Returns true if the given geometries represent the
same geometry. Directionality is ignored.
3. ST_Touches — Returns TRUE if the geometries have at least one
point in common, but their interiors do not intersect.
4. ST_Within — Returns true if the geometry A is completely inside
geometry B.
5. ST_Overlaps — Returns TRUE if the Geometries share space, are of
the same dimension, but are not completely contained by each other.
*Things to do next week*
- Write the code to provide above functionalities.
- Implement OpenLayers hooks for code.
*Reference Modules/Files* -
Hooks for Views integration -
/supporting_module/postgis/views/postgis.views.inc
*Am I blocked on anything ?*
Yes, In this week I was struggling to reflect the sample changes of PostGIS
view module in cartaro. I will discuss it with mentor/co-mentor and try to
resolve it by this monday.
