Create grid of lat long in polygon at 1 km

Question

I want all hotel list in that polygon, so I am using the Google Place API to fetch hotel info. But Google Place gives only 60 records limit, so thought to get all lat long with 1 km distance in that polygon, so I can search Google Place with 1 km, and I will get all results.

Solution I tried:

1. Create polygon in google earth and download KML file
2. Convert it into GeoJSON file
3. Now I have polygon lat long co-ordinates
4. Now I want to draw grid of lat long with distance of 1 KM in same polygon.

I want above yellow lat long which are separated with 1 km in that polygon Need list of Lat long as below yellow dot.

My data

 {
"type": "FeatureCollection",
"name": "Test",
"crs": { "type": "name", "properties": { "name": "urn:ogc:def:crs:OGC:1.3:CRS84" } },
"features": [
{ "type": "Feature", "properties": { "Name": "Test", "description": null }, "geometry": { "type": "Polygon", "coordinates":

 [ 76.95921132064926, 28.462199988668662 ] ] ] } }
]
}

Answer 1

In QGIS, load your KML polygon layer, no need to convert to GeoJSON first. Then go to Vector > Research Tools > Regular points take the extent from your layer, choose an output CRS which uses metres, say EPSG:3857, and select your spacing (to match your grid you'd want 500m), you can choose to write a file or just create a temporary layer, and run.

Creates the grid

Then export your grid as CSV (I chose WKT format for geometry) using EPSG:4326, gives:
