Historical imagery was obtained from University of Florida’s historical Imagery site, “Aerial Photography: Florida”, the Florida Department of Transportation (FDOT) Aerial Photo Lookup System, or from the FDEP district offices. Images downloaded from UF were saved locally and georeferenced by GIS team members, whereas the imagery received from the district offices were georeferenced by District staff. It is understood that these "pre-georeferenced" tiles were georeferenced within ArcMap by various staff from the District offices. The following applies to the imagery georeferenced in-office by the Division of Water Resource Management (DWRM):The georeferencing was completed in either ArcMap 10.3.1 or ArcGIS Pro. The following standards were held for the georeferencing process: the minimum number of control points was 10 points. The RMS value was kept at or below 5.0 for all tiles georeferenced in 1st Order Polynomial, and 2.0 for those georeferenced in 2nd Order Polynomial (where 1st Order was not possible). The maximum individual residual was at or under twice the RMS. Again, these were the standards, but the accuracy is not guaranteed. To QC for human error, once all counties for the given decade were georeferenced a comparison task was completed. This QC emphasized that this data is only a visual aid in that distances can be off 50 meters or more in some areas. These are mostly areas where there were limited reference features to georectify the original images. The smallest distance found was under 10 meters.

Aerial imagery from the 2003 - 2004 imagery acquisition cycle. Pursuant to Section 195.022, Florida Statutes, "Upon request of any property appraiser or, in any event, at least once every 3 years, the [Florida Department of Revenue (FDOR)] shall prescribe and furnish such aerial photographs and nonproperty ownership maps to the property appraisers as necessary to ensure that all real property within the state is properly listed on the roll." FDEP acquires orthorectified color images from the Florida Departmet of Transportation (FDOT)'s Aerial Photo Lookup System. FDEP creates this raster mosaic dataset from the orthoimages for each applicable year. Counties in this dataset are: Citrus, Clay, DeSoto, Escambia, Gadsden, Hardee, Hernando, Marion, Pasco, and Wakulla. Created 5/17/2019. Please contact GIS.Librarian@FloridaDEP.gov for more information.

The FDOT Bike Routes covers Florida following parts of US 1, US 90, US 90 ALT,and the recently added US 15. Derived from FDOT’s Roadway Characteristics Inventory (RCI) data published by Transportation Statistics Office on September 2014, FDOT‘s aerial county photography, FDOT Districts data and other external sources. Districts Staff used these data to perform a gap analysis and identify portions of US 1, US 90, and US 90 ALT, and US 15 that have bike lanes and/or shoulders next to the travel lane, with shoulder width range within 3.5 ft and 6.5 ft. These road segments were considered part of the US Bike Route, pending verification. Any identified gaps in the route were further analyzed to determine whether the travel lanes could be shared with cyclotourists or not. If they could not be shared, alternative routes were identified.The US Bike Route designation was approved by the American Association of State Highway and Transportation Officials (AASHTO) in November 2014.

This is a rectified mosaic of the individual tiles obtained from FDOT. The mosaic includes areas of Polk and Hillsborough counties where phosphate mining occurred or may occur in the future. The aerial imagery was rectified in ERDAS IMAGINE software using Autosync. The goals for rectification of each individual tile used from the FDOT included 40 control points and a RMS less than 20 pixels (pixel = 1 meter x 1 meter). RMS only measures the error against the projected image that was used as a reference during rectification. The reference image used was the 1970's SWFWMD Aerial Photography. Points not included as control points may have a larger error. The rectified tiles where then compiled into a mosaic using Mosaic Pro within ERDAS IMAGINE.

The Potential Natural Areas data layer identifies privately owned lands in Florida that are not managed or listed for conservation purposes but that are possible examples of good-quality natural communities. These areas were determined from FNAI's scientific staff vegetative interpretation of 1988-1993 FDOT aerial photographs and from input received during Regional Ecological Workshops held for each regional planning council. These workshops were attended by experts familiar with natural areas in the region. Potential Natural Areas have been assigned ranks of PNA-1 through PNA-4 (with 1 being highest value) mostly based on size and perceived quality and type of natural community present. The areas included in internal rank PNA-5 (former ACI Category C) are exceptions to the above criteria. These areas were identified through the same process of aerial photographic interpretation and regional workshops as the PNA 1 through 4 ranked sites, but do not meet the standard criteria. These PNA 5 areas are considered lower priority for conservation than areas ranked PNA 1- 4, but nonetheless are believed to be ecologically viable tracts of land representative of Florida's natural ecosystems. The original PNAs were digitized based on 1:100,000 scale county maps and lacked the geographic precision desirable for the type of geographic overlay analyses undertaken in the Conservation Needs Assessment. We therefore revised the PNA boundaries using land cover datasets, most recently by overlaying the original PNA polygons onto FNAI's 2010 Cooperative Landcover dataset (CLC). Based on comparison with digital ortho quarter quad (DOQQ) aerial photography, the CLC land cover boundaries were found to conform more closely to land cover patterns than the original PNA boundaries. In addition, the original PNAs did not take into consideration existing managed areas, Save Our Rivers (SOR) acquisition projects, or Conservation and Recreation Lands (CARL) acquisition projects that existed at the time of the original analysis (roughly 1995). We added these by selecting all CLC "natural" or "semi-natural" polygons within 1995 managed area or CARL project boundaries and 1997 SOR boundaries (all of these polygons were "clipped" by the boundaries of the managed area or CARL project). PNAs on CARL projects were assigned a rank by FNAI staff; PNAs on conservation lands and SOR projects at the time of that analysis were not ranked, they have a grid value of 100. For the April 2011 revision we added original ACI sites into the analysis for the first time. ACI sites were never ranked by FNAI scientists in the same way as PNAs, so we developed an automatic ranking system based on the acres of priority natural commmunities each site contained. ACI ranks overall are a good match for PNA ranks, but the different methodology means that the two are not entirely comparable. The April 2011 revisions also involved the demotion or deletion of some PNAs. These rank demotions and deletions were based on the percentage of the original PNA boundary filled by CLC-identified natural and semi-natural land cover. In other words, using the CLC as a representation of current landcover, fragmented PNAs were demoted and highly fragmented PNAs were deleted. Despite the revisions, PNAs have not been completely re-ranked since they were originally created in the mid-1990s. For most uses, we strongly recommend grouping PNA ranks 1-4 and 100 as one class of "high value" potential natural areas, with PNA rank 5 as a separate "moderate value" class. This avoids issues with the different methodologies used to prioritize PNAs, ACIs, and CARL projects. Please contact GIS.Librarian@floridadep.gov for more information.

This dataset depicts approximate extent ofthe runways and taxiways of the airports located within Hillsborough County. They were originally digitized from ortho-rectified aerial photos.The dataset was provided by the Hillsborough County Aviation Authority. The Hillsborough County Aviation Authority is an autonomous unit of County government, created by the 1945 Florida Legislature and charged with the operation of all publicly-owned aviation facilities within Hillsborough County, Florida. Authority owns and operates Tampa International Airport, Peter O. Knight Airport, Plant City Airport and Tampa Executive Airport. This dataset does not include all private airports within the Hillsborough County.
