Re: [datameet] Re: Facebook Road AI data!!!!!!!!!!

Hi Nikhil,

While you can always connect to the GeoPackage via a sqlite connector, and
Run Spatial SQL queries, the easiest way to create a subset, is using
GDAL's ogr2ogr utility.

If you have Qgis Installed, you would have an Os4GeoShell (For linux and
Mac, the command can be run in your regular shell).
Here, you can use ogr2ogr to transform data quite quickly, and creating a
spatial subset is as easy as passing the proper boundingbox, in a command
like this:


ogr2ogr -clipsrc 70.1 18.2 75.5 20.6 output.gpkg input.gpkg

Regards,
Devdatta

[datameet] Drainage maps of india

[Saba Mundlay]

Hey! Have you checked the irrigation and flood control department websites for 
the states you want maps for ? They are often there - you can then georeference 
these images in QGIS.

[Nikhil VJ]

I'm reading more about the .gpkg format here:

http://switchfromshapefile.org/#alternatives

Question: If I have lat-long bounds for a smaller regions, then how do 
extract that much part of data (one feature starting inside and continuing 
outwards is ok, no need to chop)... without having to load up the complete 
file into memory ?

I understand this format is SQLite at its core. And that is known for 
enabling us to query it without having to load the full data into memory.
I've been using osmconvert for extracting from .pbf, but afaik it doesn't 
support .gpkg formats.

[datameet] IMD data

[Prk]

Hi everyone, 

IMD publishes a report "Disastrous Weather Events" 
- http://www.imdpune.gov.in/library/publication.html

Their description mentions that this report is available from 1967-2016. 
However, the links only refer to 2013-2016 reports. Does anyone know if 
these are available in public domain or with IMD only? Has anyone collected 
this data? 

Unfortunately the person I was in touch with in IMD has retired so if 
anyone knows anything about these, it would be appreciated. 

P.S. the link also has some other interesting data - might be worth a visit 
for some people. 

Thank you
Regards,
Purnima

Nice PDS location data.
