VCGI is pleased to announce the rollout of more lidar image services covering all or parts of Addison, Bennington, Chittenden, Franklin, Grand Isle, Lamoille, Orleans, Rutland, Washington, Rutland and parts of Caledonia and Orange Counties. The remaining area should have services by the end of 2017. The links below will take you directly to the Rest Endpoint Page for each service. If you are not sure what to do with a Rest Endpoint Page, check out our help video on the topic:
- Lidar-based ASPECT, State Plane Coordinate System, Not Cached - http://maps.vcgi.vermont.gov/arcgis/rest/services/EGC_services/IMG_VCGI_LIDARASPECT_SP_NOCACHE_v1/ImageServer
- Lidar-based ASPECTSYM (Pre-symbolized), State Plan Coordinate System, Not Cached - http://maps.vcgi.vermont.gov/arcgis/rest/services/EGC_services/IMG_VCGI_LIDARASPECTSYM_SP_NOCACHE_v1/ImageServer
- Lidar-based SLOPE (Percent Rise), State Plan Coordinate System, Not Cached -http://maps.vcgi.vermont.gov/arcgis/rest/services/EGC_services/IMG_VCGI_LIDARSLOPE_SP_NOCACHE_v1/ImageServer
- Lidar-based SLOPESYM (Percent Rise – Pre-symbolized), State Plan Coordinate System, Not Cached -http://maps.vcgi.vermont.gov/arcgis/rest/services/EGC_services/IMG_VCGI_LIDARSLOPESYM_SP_NOCACHE_v1/ImageServer
- VCGI is aware that both slope services descriptions erroneously refer to the service units as “degree slope”, when in fact they are “percent slope”. Technical issues are blocking our efforts to correct the description. Thank you for your patience in the meantime.
- Both the ASPECT and SLOPE image services were intentionally published with the default gray scale color ramp to support flexibility for the user. For details on how you can generate derivatives on the fly using this service, please watch the March 2017 webinar on how to use the new lidar imagery services, The Powerpoint used is posted here
- The ASPECTSYM and SLOPESYM image services were published with pre-determined color ramps (that cannot be changed) to provide users with a “cartographic ready” option.
- ASPECT and SLOPE data used in these services are not yet completely available for download (soon!)
VCGI is pleased to announce that Esri has integrated the 2016 VT Orthoimagery (30cm + 15cm “buy-ups areas”) into their World Imagery Service (https://www.arcgis.com/home/item.html?id=10df2279f9684e4a9f6a7f08febac2a9). The 2016 leaf-off imagery covers a swath spanning an area covering most of Rutland and Windsor Counties.
VCGI decided to go beyond data access, analysis, and visualization for a change and reached out to cartographers and artists seeking examples of how maps and place-based art help us find our place in Vermont. We are thrilled to share these thought-provoking perspectives on maps and place. If you’d like to imagine music playing while you peruse, try “Stand” by R.E.M: “Stand in the place where you are. Think about direction, wonder why you haven’t before…”

VCGI is pleased to announce the initial rollout of lidar image services covering all or parts of Addison, Bennington, Chittenden, Franklin, Grand Isle, Lamoille, Orleans, Rutland, Washington, Rutland and parts of Caledonia and Orange Counties (see map below). The remaining area should have services by the end of 2017. The links below will take you directly to the Rest Endpoint Page for each service.
- Lidar-based Digital Elevation Model (DEM), State Plane Coordinate System, Not Cached - http://maps.vcgi.vermont.gov/arcgis/rest/services/EGC_services/ IMG_VCGI_LIDARDEM_SP_NOCACHE_v1/ImageServer
- Lidar-based Hillshade, State Plan Coordinate System, Cached (see note below!) - http://maps.vcgi.vermont.gov/arcgis/rest/services/EGC_services/ IMG_VCGI_LIDARHILLSHD_SP_CACHE_v1/ImageServer
- Lidar-based Hillshade, Web Mercator Coordinate System, Cached (see note below!) - http://maps.vcgi.vermont.gov/arcgis/rest/services/ EGC_services/IMG_VCGI_LIDARHILLSHD_WM_CACHE_v1/ImageServer
- The DEM image service was intentionally published with the default gray scale color ramp to support flexibility for the user. For details on how you can generate derivatives on the fly using this service, please watch the March 2017 webinar on how to use the new lidar imagery services http://vcgi.vermont.gov/events/archive#webinar (the powerpoint used is also linked from the event archive).
- The Hillshade services are being initially release without first being “cached” in order to make them available as early as possible while the time intensive cache generation process is conducted.
- All of the DEM data in these services are also available for download: Keyword search at geodata portal on 0.7 meter will bring these and other high resolution elevation products to the top of the search results list.
- Associated contour data (both 1’ and 2’) are also available: Keyword search on 1 ft contour and 2 ft contour work well.
