GeoIP2 expanded fields: continents and country registered

Base platform is fedora 38

sudo dnf install -y libmaxminddb libmaxminddb-devel

sudo dnf install -y geolite2-city geolite2-country geolite2-asn

download geolite2++, unpack

ccmake . to configure

make

Here are the various APIs to GeoIP2. And some idea of the continental slices. Background IP Geolocation Data for schema fields and metadata.

For the C++ API, use GeoLite2++ and here are the docs. Just use the pre-built binary from rizal.

To purchase a one-time GeoIP2 City-level database in binary format from MaxMind, go here. Stash the updated files in /usr/share/GeoIP.

The source interface is in the alpha60 file “a60-geo-maxmind-2.h”, and uses the following databases directly:

“/usr/share/GeoIP/GeoLite2-Country.mmdb”

“/usr/share/GeoIP/GeoLite2-City.mmdb”

“/usr/share/GeoIP/GeoLite2-ASN.mmdb”

Cartography Futures

1.dymaxion to authagraph to myriahedral projections

Buckminister Fuller and co-cartographer Shoji Sadao, designed an alternative projection map, called the Dymaxion map. Since then, several other projections have been proposed that evolve the idea of map projections in a similar manner. Favorites are:

• authagraph
• myriaworld
• unfolding the earth myriahedral projections

2. new approaches to population density, use natural earth data and then read the shapefile with python

3. pyshp
https://pypi.python.org/pypi/pyshp

 

4. geospatial python

5. example api

• get projection
• get shapefile

Ben Fry Geospatial

Processing started with a map of zip codes. Since then, Ben Fy has made some extraordinary maps of the United States, a few of which are listed below.

1. zipdecode. How does the postal code numbering work in the United States?

2. allstreets.
