Consulting services

We have developed analytic processes and brought reliable and understandable evaluations on issues ranging from controlling deadly diseases to primary care access. Working for major actors such as the City of Philadelphia, PA, United States, or the Regional Ministry of Health in Areaquipa, Peru SpatialControl has produced a variety of deliverables, from reports to interactive websites.

Our team leader is currently a research faculty at the Institut National de la Recherche Agronomique (INRA), in France. Prior to this position he was a researcher for four years at the Perelman school of Medicine at the University of Pennsylvania. This prior work has led to over 10 academic papers in leading statistical and medical journals, gathering over 150 citations by academic pears.

The ability to implement multiple analytic techniques using several programming languages allows SpatialControl to imagine deliverables tailored for your needs. With over 10 years of experience in scientific calculus and expertise we insure optimal reliability, flexibility, reproducibility and development speed for our projects.

tmap R package

R has been my environment of choice for plotting spatial data for some time now and this great piece of software got even better with the tmap package.

It easily allow to plot maps such as :

You plot using the function `qtm` and can easily customize the map by providing options to intuitively named subroutines such as tm_fill.

I specially love the different algorithms proposed to choose the classes for the legend, quantiles, k-means … You can simply plot the above with:


library("tmap")
data(World)
qtm(World,fill="pop_est_dens",fill.style="quantile",
fill.palette="Blues")

where fill simply is the name of the field in the data frame, fill.style is the algorithm used to make the classes of colors and fill.palette the name of the pallette that can be checked up using :

RColorBrewer::display.brewer.all()

Check up the help for tm_fill to understand the fill.xxx parameters!

Two thumbs up for tmap!!!

News coverage for the access to care in Philadelphia study

Wednesday, May 8th was the official release date for the report on access to primary care in Philadelphia.

We’ve got some nice coverage of our study by the LDI periodical of course but also by NewsWorks and Philly.com (Philadelphia Inquirer).

Cheers!

Quick and easy cartography with “My Maps”

For quick and easy cartography, “My maps” service from Google allows to make and publish online maps.

Adding features

A csv with coordinates can easily be uploaded. It also supports drawing of points, polygons and polylines on multiple layers.

Maps are easily modifiable using a smartphone: a must have for field cartography :-)

Export

Note that the export format is kml/kmz. The kmz exported can be unzipped with any zipping utility returning a kml. The kml can be imported directly in R using readOGR in the the rgdal package. It can also be imported in QGIS and from there exported to many formats.

Delivery of the review report on Access to Care in Philadelphia

This significant expertise on the access to primary care in the Philadelphia, PA involved several of our key know-how:

  • Data Management with merging of practitioners and population information from over 10 data sources
  • Spatial analysis based on driving distances
  • Cartography with the constitution of interactive Google maps involving spatial statistics under the hood
  • Web development to interface the whole

It is reaching an end with the recent delivery of the review report.

Our next steps are to:

  1. Make available online the interactive map engine, without proprietary data :-)
  2. Publish in medical journals the key findings of the study (yes, access to care has social determinants…)

We will keep you posted.

Cheers!
