Python for Street Network

Thanks to Lillian Coral of LA City for passing this interesting set of tools along:

OSMnx is a Python package for downloading administrative boundary shapes and street networks from OpenStreetMap. It allows you to easily construct, project, visualize, and analyze complex street networks in Python with NetworkX. You can get a city’s or neighborhood’s walking, driving, or biking network with a single line of Python code. Then you can simply visualize cul-de-sacs or one-way streets, plot shortest-path routes, or calculate stats like intersection density, average node connectivity, or betweenness centrality. You can download/cite the paper here.

In a single line of code, OSMnx lets you download, construct, and visualize the street network for, say, Modena Italy:

The Undiscovered Country

If you are a regular user of PostGIS, you probably already know that Paul Ramsey is its most well known champion. In a keynote he gave at Geomatiqué 2016 in Montreal, he provided some insights on where GIS is evolving.

He explained how GIS tends to lag about five years behind most other technologies. Concepts like Big Data, the Internet of Things, and Machine Learning are not all that new. What drives technological change is not the breakthroughs as much as the mass accessibility to those breakthroughs.

Yes, he borrowed the title of his presentation from Star Trek VI, but if you take the time to go through his well remarked slides, you might really enjoy his insights into how our GIS infrastructure is changing. You’ll see the often recurring quote,

“First it becomes possible, then it becomes so cheap that anyone can do it… and that’s where it gets interesting.”

San Diego International Airport Interactive Map

San Diego International Airport developed an interactive map (mobile Geocortex viewer) to show locations for dining, shopping, relaxing, etc. with photos and information. I think it’s worth checking out!

Intro to GIS Course and Online GIS Certificate at UCLA Extension

UCLA Extension is offering an online Introduction to GIS course starting on January 16, 2017.  Enrollment is open to the public and will continue until January 23, 2017.

This course is the first course in UCLA Extension’s online certificate program in geographic information systems (GIS) and technology.  This fully-online, one-year certificate program provides a comprehensive introduction to state-of-the-art methods and techniques within the field of geographic information systems (GIS) and geospatial technology. All courses are designed to accommodate the schedules of working professionals, and no prior GIS experience is required or assumed. Participants who complete the program can expect to be sufficiently prepared for an entry-level job in GIS and/or related geospatial industries.

Registration and more information can be found at: https://www.uclaextension.edu/LandingPages/Engineering/gis.html

Intro to GIS Course at Santa Monica College

Santa Monica College is offering an Introduction to GIS starting on February 16, 2017.

Description:
GIS 20, Introduction to Geographic Information Systems, 3 units

Transfer: UC, CSU   •   Prerequisite: None.

GIS are computer-based systems used to collect, store and analyze geographic information. This course will present the concepts of Geographic Information Systems (GIS) science and its applications to spatial data management. Topics include: Identification and acquisition of GIS data; Assessment of vector and raster systems, scale, resolution, map projection, coordinate systems, georeferencing and Global Positioning Systems (GPS). Spatial analysis and modeling with GIS will also be presented.

GIS 20 is the same course as Geography 20. Students may receive credit for one, but not both.

2017 GISP Map Contest

The GIS Certification Institute (GISCI) is proud to announce its 2017 Map Contest.

This year’s challenge is to show us how GIS can be, or has been, used in either disaster preparation, response, or recovery. Scenarios can be real or imagined. More information is available, including eligibility and prizes, on GISCI Announcements.

The GISCI Outreach Committee extends its heartfelt apologies for not having 2016’s winning entries displayed at last year’s Esri User Conference Map Gallery, due to GISP Exam scheduling logistics. All efforts will be made to not repeat those mistakes this year.

The GISCI does have high hopes for a high number of contestants in 2017. After all, when it comes to disaster planning, are not GIS professionals considered heroes-in-waiting?
