National Centre for Flora Conservation
For the latest five years I have been build the national platform for brazillian risk assessment of flora, CNCFlora.
The platform consists of a series of independent services that talk to each other, in a micro-services maner.
Techs included: CouchDB, ElasticSearch, Docker, Ruby, Clojure, PHP, and many others.
View the project source code organization.
A big index of biodiversity quality and geospatial analysis, performed on the 50k species of Brasil flora with circa 5M occurrences.
The micro-services are composed of these parts:
- dwc-bot: a clojure bot and API to index occurrence data in SQLite
- taxadata: a PHP webservice for taxonomy data in SQLite
- dwc-services: clojure webservice to make analysis on occurrence data
- biodiv-idx: clojure bot to unify the others and index on elasticsearch
- biodiv-ui: PHP user interface to view the result
All done inside docker and deployed on
Digital Ocean ScaleWay.

Clojure OpenStreetMaps lib
A efficient library to read OSM dump files in clojure, writing GeoJSON and also capable of sending to webhooks. Includes a Command Line Iinterface.
Clojure TopoJSON lib
A very efficient library to read and write TopoJSON in clojure, a much more compact topological format for geospatial data.
Clojure GeoTIFF lib
An experimental efficient library in clojure to read data from GeoTIFF files.
Leaflet Table and Landsat
A plugin for the leaflet map library to add lightweight data table from a layer, and another to include landsat/modis imagery where you can choose the date of the images.
