Duplicated grids for hrsl_ph_500m_grid_v1.geojson.zip

[maning]

During mapping of Siquijor we discovered that some grids were queued for mapping and validation several times.
See screenshots below, darker grids means duplicated polygons.

Actual polygons used for creating the projects

It looks like the grids are duplicated along the edges of municipal boundaries.

Next actions

• Inspect the whole dataset if this is persistent in across
• Re-generate the 500m grids to remove duplicates

I confirm that this is prevalent in the countrywide data and not just in Siquijor. Duplicate occurs when parts of the grid is associated with different municipal boundaries. This might have occurred when we did a spatial join between the grid and the admin boundaries.

Darker grids not just in Siquijor but on other islands like Cebu and Negros.

Grid in red selected using Identify tool is part of the 3 ADMIN3PCODE.

I'll run another process to make sure one grid is assigned to only one PCODE.

This was caused by my mistake when I joined the grid polys to ADMIN3PCODE. Instead of a one-to-one join I used one-to-many! 🤦‍♂

Revised poly in a PR in a bit. Result of the fix below:
