How To Interpret a Satellite Image

This is a good read; and not too long.  From Earth Imaging Journal, January/February 2014.

Five basic strategies will help you discover a wealth of knowledge.

Reminder – no eGIS Meeting tomorrow

Just a reminder that we will be meeting on the 29th instead.

LA County GIS Data Portal adds instructional videos

instructional_videosWe have a pair of instructional videos for the LA County GIS Data Portal that will help you make better use of the data.  The first video shows you how to find and download GIS data from our site, while the second shows you how to use free software to begin making maps with our free data.

Thank you Public Works, and John Hickock in particular, for making this for us!

FOSS4G 2014 Registration Opens

FOSS4G International ConferenceToday, registration opens for the annual international FOSS4G conference (Free and Open Source Software for Geospatial).

Organized by OSGeo, this year’s event returns to North America via Portland, Oregon, U.S.A. and takes place September 8-13.

To learn more about the workshops, presentations, social events, and the people who make it happen, visit FOSS4G 2014. If you have an interest in open source GIS but don’t plan to make the 1,000 mile trek to Oregon, plenty of information is available online. The FOSS4G 2013 site will provide a rough idea of what was done last year, and some of those presentations can be found on YouTube.

TileMill and Mapbox

TileMill is a free and open source desktop application that runs on Windows, Mac, and Ubuntu. As the name suggests, TileMill produces a set of cached image tiles, while Mapbox provides a means to host your cache online, using Open Street Map as a base.

A few weeks ago, I tried out the free plan and used TileMill to create this map from our City Boundary shape file. (This map might not render if you are using an older browser. I had better luck with Chrome.)

On the positive, you can make a lean, quick, online map that is both PC and mobile phone friendly. On the negative, the free plan’s limited space caused me to run out of tiles at larger scales; at least some of the paid plans seemed reasonable.

If you are attending CalGIS 2014 and you’d like to know more about TileMill, Eric Gundersen, CEO of MapBox, will be one of this year’s featured speakers.

Choosing a mobile development Strategy

ESRI wrote a very nice article about the various technology decisions when selecting a mobile development strategy.  It isn’t GIS centric nor esri centric, so I highly recommend it.

Choosing a mobile development strategy introduces many parameters: a team’s development skillset, the application’s required functionality, and the ease of maintenance, just to name a few.  Compared to desktop technology, mobile technology is still in its embryonic stage and rapidly evolving.   This post examines three models of mobile application types: Web, Hybrid and Native.
