We now have the latest version of the New York City Planning Tax Lot Layers; MapPLUTO 09 V1 is here and includes data updated through Spring of 2009. MapPLUTO models tax lots throughout New York City. This dataset represents a compilation of data from various government agencies throughout New York. The attribute data pertains to tax lot and primary building characteristics and information related to administrative and political districts for each tax lot in New York City. The underlying geography is derived from the Department of City Planning’s Tax Block and Tax Lot Base Map project.
The datasets are only available in the EDS lab during lab hours.
We have recently acquired a variety of datasets for features in Mumbai, India. Digitized from maps at a scale of 1:7500, a total of 6 layers representing streets, water bodies, railroads, points of interest, boundaries and oparks are available. Metadata records are now retrievable from the CU Spatial Data Catalog. Remote access is available to these datasets for current CU affiliates via UNI.
We have recently aquired a variety of datasets for features in Venice, Italy derived from the NAVSTREETS database. A total of 30 layers representing building footprints, streets, waterways, railroads, points of interest, facilities, boundaries and other features are available. Metadata records are now retrievable from the CU Spatial Data Catalog. Unfortunately we cannot deliver these datasets remotely, but you can visit the EDS lab for access.
We recently purchased a layer from Platts representing major electric transmission lines throughout North America. Attribute information includes owner, voltage, company, category, length, circuit, transmission type and substation information. This dataset meets or exceeds the National Map Accuracy Standards for geospatial data at a 1:250,000 map scale and is available for download from our spatial data catalog.
This summer we acquired the 1996 ArcAtlas: Our Earth collection from ESRI. The atlas features dozens of datasets representing a wide ranging array of features, including climatical, geological, biological and political characteristics as well as physical facilities. We have merged most of the ArcAtlas layers to create world-wide coverages, and these new datasets are available for download from the CU Spatial Data Catalog.
We’ve been working all summer to add records for our newer datasets in the CU spatial data catalog. We will be detailing some of these new additions over the next few days. Of notable interest is the addition of the vector layers for the 2008 ESRI Data & Maps Collection. These layers include a variety of data types from throughout the world and are in ESRI’s compressed Smart Data Compression (SDC) format. They can also be downloaded remotely for current Columbia affiliates. Please note that most of the superseded data layers from previous years’ collections have been removed from the catalog in order to make finding the most recent data easier. If you do require any of the older editions, please come see us in the EDS lab.
The Harvard Geospatial Library has a whole new look and feel, using OpenLayers for the display and navigation map.
Searching and browsing datasets is also much improved, including the updated advanced search option.
A good portion of the 6,500+ records are publicly downloadable which makes this an amazing resource even for non Harvard affiliates.
I’m very impressed with what they’ve put together.
The CU Spatial Data Catalog now contains 21 records for datasets in KMZ format. These datasets were produced by EDS in partnership with the Columbia Center for New Media Teaching and Learning (CCNMTL) for use in the Journalism 6001 (Reporting and Writing I) and Religion 2800x (Religion and the Modern World) courses.
However, we are making the layers available for download to Columbia affiliates, including datasets detailing crime data, land use, census data, and transportation maps in New York City.
