Description: A point feature class of open DERM Contaminated sites - see phase code for status of site. Contaminated sites identifies properties where environmental contamination has been documented in the soil or groundwater. Facilities get listed as a contaminated site by a DERM inspector who finds a violation on the property. Facilities that store potential contaminated materials are permitted and/or tracked by DERM. A site is removed from the active contaminated sites layer/list when the sites is found by DERM to be cleaned up.

Description: A collection of vector polygon features for water bodies within the Urban Development Boundary (UDB) and outside the UDB, approximately 938 square miles. The planimetric layer for Miami-Dade County was previously digitized in 2001 by Woolpert, in 2012 by GPI Geospatial (GPI), and in 2020 by GPI. GPI’s 2022 update utilized a Geodatabase provided by ITD for Miami-Dade County containing two layers to be updated: Water and Edge of Pavement. GPI used the recent set of county orthoimages, produced by Woolpert in 2022, to perform the update of the various feature classes. The feature classes were clipped into smaller blocks. Compilers made adjustments or recollected any missing features. The corresponding attributes were assigned to each separate shapefile as adjustments and new collection occurred. The shapefiles were then merged back together into a full file. Topological checks were performed to make sure the linework didn’t cross unexpectedly, ends dangled, or strange gaps exist in the collected features. Depending on the layer, different checks were done using the existing data layer to evaluate the completeness of the overall collection. The final layers were quality checked for formatting and file corruption before being sent to the client for review. Personnel that collected this data are either photogrammetrists trained in stereo collection or editors trained in ortho-photography based collection. Items included in the feature class WATER BODIES (Polygons) are: Water bodies and water-under-the-bridge features Definition of particular fields in the Water feature class: Water = {0,1} where 0 = Feature does not represent water; 1 = Water feature. Type = {"", "B"} where B = Water under the bridge. Where "" marks water locations without bridges. Possible combinations of these fields are: 0,""; 1,"";1, "B".

Description: A collection of vector polygon features for water bodies within the Urban Development Boundary (UDB) and outside the UDB, approximately 938 square miles. The planimetric layer for Miami-Dade County was previously updated in 2007 by Woolpert and in 2012 by GPI Geospatial (GPI). GPI’s 2020 update utilized a Geodatabase provided by ITD for Miami-Dade County containing three layers to be updated: Water, Edge of Pavement and Rails. GPI used the recent set of county orthoimages, produced by GPI in 2019, to perform the update of the various feature classes. The feature classes were extracted from the geodatabase and converted to VR files with a layer created for every attribute combination. Compilers made adjustments or recollected any missing features in a new file. This process was done to keep adjustments separate from the original data provided. After all the adjustments were completed, the different layers were converted individually back into shapefiles. The corresponding attributes were assigned to each separate shapefile. The shapefiles were then merged back together into a full feature. Topological checks were performed to make sure the linework didn’t cross unexpectedly, ends dangled, or strange gaps exist in the collected features. Depending on the layer, different checks were done using the existing data layer to evaluate the completeness of the overall collection. The final layers were quality checked for formatting and file corruption before being sent to the client for review.

Description: A generalized polygon feature class of Miami-Dade County water bodies with the land features removed.This feature class is a derrivative of the 2012 planimetric water layer. It was Generalized using the Cartographic Generalization tool, Simplify Polygon with the Bend Simplify option and a Minimal Allowable Offset tolerance of 5 feet. Additionally the land feature(s) was removed.A collection of vector polygon features for water bodies within the Urban Development Boundary (UDB) and outside the UDB, approximately 938 square miles. The planimetric layer for Miami-Dade County was previously updated in 2007 by Woolpert. Aerial Cartographics of America's update is comprised of two individual updates: inside the UDB (542 square miles) performed using a on-screen/2D digitizing of the 2012 orthophotography captured by PhotoScience; and outside of the UDB (396 square miles) using on-screen/2D digitizing of the 2012 orthophotography captured by PhotoScience. Personnel that collected this data are either photogrammetrists trained in stereo collection or editors trained in ortho-photography based collection. Items included in the feature class: WATER BODIES (Polygons) Water lines and water under the bridge.Definition of particular fields in the Water feature class: Water = {0,1} where 0 = Feature does not represent water; 1 = Water feature.Type = "C" = canal, "L" = Lake and "B" = BayReason: Add WaterG2012 layer to production. Removed 1 feature below 35 square feet. During an analysis of the land features, it was found that only 1 of the 7 features designated as land was actually land. 6 features were reattributed to water and 1 land feature was removed from the dataset.

Description: This dataset is used in the Atlas of ReUrbanism | Miami web application. The Atlas of ReUrbanism is an evolving and expanding tool, allowing users to explore the built environment of American cities, block by block. Using our maps, you can interact with data on your city's built assets, and click to layer demographic, economic, and environmental data from the US Census, American Community Survey, and more. The maps focus on the Character Score for buildings and blocks across 50 U.S. cities, as established in the Preservation Green Lab’s Older, Smaller, Better report. Individual building and block characteristics are also selectable and viewable.A resource on the American built environment, the Atlas of ReUrbanism is a product of the Preservation Green Lab and part of the National Trust for Historic Preservation’s ReUrbanism initiative.Learn more at atlasofreurbanism.com.
