Announcement: WMS restored to imagery and DEM services
We are pleased to announce that WMS capability has been restored on our orthoimagery and DEM image services. Services which previously had WCS capability will have both WMS and WCS capabilities.
Notice: Maine GeoLibrary COVID-19 Content discontinued
As Maine's COVID-19 response efforts shift to long-term focused support, the Maine Office of GIS (MEGIS) has ended updates of its COVID-19 GIS content. This means that Tuesday, May 31, 2022 was the final day of updates for all MEGIS COVID-19 data tables, feature layers, web maps, and dashboards. The Maine CDC is continuing to track and report COVID-19 data; to access its data and dashboards, please visit the Maine CDC Coronavirus 2019 (COVID-19) page at: https://www.maine.gov/dhhs/mecdc/infectious-disease/epi/airborne/coronavirus/data.shtml.

MaineIT completed a system update on 4/3/2021 that restored normal access to the full resolution imagery services hosted by the Maine Office of GIS. The services have been tested and monitored over the last 48 hours and have maintained consistent service over that period. Please feel free to return to normal use of these services to support your GIS workflows. If you experience disruption of normal imagery access, please note the specific image service failure and the time and email your information to the Maine GeoLibrary at GeolibraryBoard.OIT@maine.gov

The intermittent problem resulting in GIS image service dysfunction has returned. The Maine Office of GIS has confirmed the root cause is not within the Enterprise GIS itself. Maine IT and the Maine Office of GIS have an ongoing effort underway to determine the source of this issue. We do not yet have an ETA for resolution; we will update this posting when the services return to normal. GIS users may find the following imagery service alternatives helpful in the interim:
- ESRI imagery accessible directly from the GIS desktop applications
- NAIP from USDA-FSA: https://gis.apfo.usda.gov/arcgis/rest/services
- The National Map:

GIS image services have returned to normal function. MaineIT applied an update to the storage environment that appears to have had a positive impact on service. The Maine Office of GIS is monitoring and collecting data to help affirm this is a longer term fix. In the meantime, please feel free to resume regular use of these services. If users encounter a renewal of the imagery performance issue, or any newly impacted items, please reach out to us with details.
March 10, 2021 - Disruption to Imagery Services
The intermittent problem resulting in GIS Image service dysfunction has returned this morning. We have affirmed the root cause is not within the Enterprise GIS itself. MaineIT and MEGIS have an ongoing effort underway to determine the root source of this intermittent problem.

Maine GeoLibrary Update September 18, 2020: Crown of Maine LiDAR & 2' Contours for Crown of Maine
Hello Maine GeoLibrary Data Catalog Consumers,
Good news! The Crown of Maine LiDAR project is now available through the Maine GeoLibrary Data Catalog (https://www.maine.gov/geolib/catalog.html#elevation).
This project encompasses the northern portion of Maine and covers 6,732 square miles. LiDAR data was captured and processed to meet USGS Quality Level 2 (QL2) accuracy standards. Approximately 2/3 of the project was acquired in the spring of 2018, but due to sensor issues and leaf-out conditions, the middle portion of the project was not captured in 2018, but in the spring of 2019. Actual date ranges are from May 12, 2018 through June 8, 2019.
The State of Maine serves derivative products (Digital Elevation Model (DEM), and contours in the near future) from this dataset and they are available through the Maine GeoLibrary Data Catalog (https://www.maine.gov/geolib/catalog.html#elevation).
The LiDAR point cloud data will be made available through The National Map (TNM) and the United States Interagency Elevation Inventory (USIEI) sites by the end of the year (estimated).
Two-foot contours in vector format are also part of this Crown of Maine deliverable and will be made available in the mid-October timeframe. Stay tuned for an updated announcement on delivery and availability dates.
Sincerely,
Claire Kiedrowski Executive Director
Maine Library of Geographic Information

Orthoimagery 2018 Dynamic Re-Projection Inaccuracy UPDATE
Hello Maine GeoLibrary Data Consumers,
UPDATE: Maine GeoLibrary Orthoimagery 2018 dynamic reprojection inaccuracy has been corrected by applying applicable transforms to our services. For reference, the native projection is http://www.epsg-registry.org/export.htm?wkt=urn:ogc:def:crs:EPSG::6348, https://epsg.io/6348

Orthoimagery 2018 Dynamic Re-Projection Inaccuracy
Dear Geospatial User,
*****NOTICE: Dynamic reprojection of Maine GeoLibrary Orthoimagery 2018 in some environments, including ArcGIS Online Web map, may display inaccurately. The approximate value of the observed inaccuracy is one meter displaced southerly. The cause of this error has been determined and a fix is scheduled for Sunday August 4, 2019. NOTICE*****
Thank you for your patience while this issue is resolved.

Crown of Maine LiDAR Update
Dear Geospatial User,
Good news: the "Crown of Maine" LiDAR acquisition was completed in late May and early June. You may recall that this project was not completed in 2018 due to sensor and weather issues, but I am pleased to let you know that between the original acquisition in 2018 and this spring's acquisition in 2019, we now have a complete dataset for this area:
The processed and edited dataset is scheduled to be delivered to USGS in late 2019, with an anticipated delivery to the State of Maine in early 2020.
You can also track the status here: https://www.maine.gov/geolib/programs/lidar/index.html
I will keep you updated as the project progresses.
Sincerely, Claire

Subject: Update on 2019 Maine Orthoimagery Program
Good afternoon, I have news to share with you on the 2019 Maine Orthoimagery program! Please see the image below for a status on the 2019 Program. Note that the color of the flight line indicates the following:
? ORANGE = Not flown
? GREEN = Passed Quality Control
? RED = Re-flight needed
These communities were flown for 4-band orthoimagery this past May under ideal leaf-off, minimal snow conditions:
? 3" ? Bangor, Camden, Rockport, Thomaston
? 6" ? Biddeford, Brewer, Hampden, Freeport*
? 12" ? Knox County
? 18" ? Androscoggin, Kennebec, and Sagadahoc Counties**
*Due to weather and ground conditions, we were not able to capture suitable imagery for Bridgton, Naples, China, or Cushing, but they are all scheduled for next Spring 2020.
** A few areas for the 18" county acquisitions may need to be re-flown due to clouds, cloud shadow and other (even though the entire line is shown in red indicating a re-flight, it really is just specific areas). These are minimal issues and will be addressed during the Quality Control process. If needed, impacted tiles will be re-flown during the Spring 2020 acquisitions and updated tiles will be delivered.

Raster Data Migration - mapserver.maine.gov retired
On Friday January 4, 2019, the portion of our legacy GIS Enterprise hosting much of our raster data was shutdown. All content that had been hosted at http://mapserver.maine.gov continues to be accessible in the Maine GeoLibrary Data Catalog at https://maine.hub.arcgis.com .
These same data and services may also be accessed directly via a web browser, GIS/CAD client or programmatically at https://gis.maine.gov/arcgis/rest/services . Users choosing to access data services directly from the REST service directory should recognize the use of ISO 19115 Topic Categories for folders containing services. Looking for orthoimagery? Explore the imageryBaseMapsEarthCover folder; Contours? Explore the Elevation folder.; Parcels? Explore planningCadastre folder; etc.
