Summer GIS Workshops


gis_logo_smallWe’ve put together a GIS workhsop series starting this week Wednesday 5/25 and running just about every Wednesday  through early August.

The workshops focus on both core GIS skills such as understanding coordinate systems & projections, georeferencing and geocoding and a couple workshops focusing on Model Builder, ArcPy, Google Earth Pro and working with KML.

The Intro to GIS workshop is this Wednesday, 5/25 at 11am in Lehman Library, room 215. Registration is now open.

With the exception of the Model Builder and ArcPy workshops, attendance to a previous workshop isn’t necessary, just keep in mind that most workshops require some basic knowledge of GIS to attend.


GIS workshop – working with ArcGIS & Google Earth

We’re offering a workshop on ArcGIS & Google Earth on Friday November 20th in EDS from 10:30am – 12:30pm.


I plan on covering and comparing some of the tools for exporting vector layers into KML & KMZ format.

I’ll also discuss symbolizing and labeling data,  adding a legend as a screen overlay, and importing Google Earth layers into ArcGIS.

An introductory level knowledge of ArcMap is required to attend the workshop, registration opens one week before.

NYPL Mapping NYC

Matt Knutzen has done an amazing job putting together a KMZ index of digitized NYC map collections from the NYPL Map Division.

Check out his post with some recommendations on how to use it, and then download it.

There’s also a short video called Mapping the World which is part of the Treasures of NYPL Video Series which is worth checking out.

It’s narrated by both Alice Hudson, the Chief of the map division and Matt Knutzen, the Assistant Chief.

Meiji era Kantō region web map

Historical Agricultural Environment Search System (rough translation of 歴史的農業環境閲覧システム)

For those of you who are interested, there is a new web mapping service up showing seamless georeferenced maps of the Kantō region in Japan during the early to mid Meiji era. Overlayed on top of this are current road, river, and land use to view change. And as a added plus, a KMZ file is also available to view the full Meiji era maps in Google Earth,which ran a little slow when I tried it but was worth the wait.

Although the site is entirely in Japanese, it’s still easy enough to navigate around if you can’t read the characters.

Either choosing a location from the right hand side or just clicking on one of the places (marked by red circles) on the map opens up the mapping application – all the components are open source. If you overlay the 1997 land use data (it’s a little coarse compared to the 1880 data) you can see some of the changes.

The legend for the 1997 land use data on the map is in the FAQ – here’s a rough translation.

Left column – rice field (水田), other agriculture (その地農用地), forest (森林),  waste or unused land (荒地), built up area (建物用地)

Right column – transportation (幹線交通用地), other land (その地の用地), water bodies (河川および湖沼), beach (海浜), golf course (ゴルフ場)

If anyone has a better translation let me know and I’ll update the English categories.
