Inventory scope
Countywide GIS resources, including Rochester; free and paid products coexist.
Custom gateway verified; linked gallery/enterprise resources19 plus explicit public Open Data group21 yield40 unique official ArcGIS listings, not40 downloadable datasets. One listed EagleView/Pictometry WMTS is vendor-hosted and excluded as data under official-host-only rule.
Public group exposes parcel/address/roads/boundaries/building footprints/parks-trails/elections/education plus2021 QL0 LiDAR-derived DEM/DSM/hillshade/intensity/canopy/NDVI/NAIP and statewide MnTopo/TRS references. Tree canopy has no accuracy study; terrain derivative edges may stretch; statewide TRS source maps1976–1994 are not county-maintained survey boundaries.
Nested viewer publishes land-use/zoning and city-specific plans, flood fringe/FEMA, PLSS, highway ROW/bridges/traffic signals/ROCOG2045, heritage preservation hidden within Parcels_Addressing/7, wetland conservation applications (not building permits), Decorah Edge/springs/seeps/buffers, karst/sinkholes/bedrock/pollution sensitivity and soils. Contour tiles and layer groups are counted separately from unique datasets.
Gateway explicitly says most products are direct purchase OR no-cost download. Current-owner/address mailing lists $45/list; subscriber map has daily/monthly/yearly fees and current-owner/address extraction. These are not promised free because public GIS services exist.
Shopping cart endpoint returned403 this turn; do not promise purchases/downloads work. No cart retry, contact, login, transaction or binary download.
