description: The primary objective of the project is to develop an integrated ecological and socioeconomic land use evaluation model (the Ecosystem Portfolio Model, EPM) for Department of the Interior (DOI) resource managers to use to reconcile the need to maintain the ecological health of South Florida parks and refuges with increasing pressures for higher density development in the agricultural lands outside of the Urban Development Boundary in Miami-Dade County. The EPM has three major components: (1) an ecological value model based on ecological criteria relevant to National Park Service and US Fish & Wildlife Service resource management and species protection mandates; (2) a real estate market-based land value model sensitive to relevant land use/cover attributes indicative of conservation and development decisions; and (3) a set of socioeconomic indicators sensitive to land use/cover changes relevant to regional environmental and ecological planning. The current version is implemented for Miami-Dade County, with the protection of ecological values in the lands between the Everglades and Biscayne National Parks as the focus. The first two components have been implemented in the GIS web-enabled prototype interface and the third component is being developed in draft form in FY08 in consultation with the Florida Atlantic University Dept of Urban and Regional Planning.; abstract: The primary objective of the project is to develop an integrated ecological and socioeconomic land use evaluation model (the Ecosystem Portfolio Model, EPM) for Department of the Interior (DOI) resource managers to use to reconcile the need to maintain the ecological health of South Florida parks and refuges with increasing pressures for higher density development in the agricultural lands outside of the Urban Development Boundary in Miami-Dade County.

The global real estate surveying and mapping market is experiencing robust growth, driven by the burgeoning construction industry, increasing urbanization, and the rising demand for precise land information for real estate development projects. The market, segmented by application (urban planning, real estate development, others) and type (land surveying & mapping, house surveying & mapping, others), shows significant potential across various regions. While precise market sizing data isn't provided, considering the involvement of major players like Trimble, Fugro, and AECOM, and the rapid expansion in urban areas globally, a conservative estimate places the 2025 market value at approximately $15 billion. A Compound Annual Growth Rate (CAGR) of, say, 7% (a reasonable estimate given industry growth trends) projects significant expansion over the forecast period (2025-2033). This growth is fueled by technological advancements, particularly in Geographic Information Systems (GIS) and drone technology, enabling faster, more accurate, and cost-effective surveying and mapping. Furthermore, increasing government regulations and emphasis on sustainable development are pushing for better land management, further boosting market demand. Key restraints include the high initial investment costs associated with advanced surveying technologies and the need for skilled professionals capable of operating and interpreting data from these technologies. However, the long-term benefits of improved accuracy, efficiency, and reduced risk outweigh these initial hurdles. Regional variations exist, with North America and Europe currently dominating the market due to higher adoption rates of advanced technologies and established real estate sectors. However, rapid urbanization in Asia-Pacific and other developing regions is expected to drive substantial growth in these areas in the coming years. The market's future trajectory is positive, with opportunities for companies to innovate in data analytics and integrate AI for enhanced decision-making in real estate projects. This increased sophistication in data analysis translates to improved efficiency, reduced errors, and better-informed investment decisions.

This dataset visualises the spatial distribution of the rental value in Amsterdam between 1647 and 1652. The source of rental value comes from the Verponding registration in Amsterdam. The verponding or the ‘Verpondings-quohieren van den 8sten penning’ was a tax in the Netherlands on the 8^th penny of the rental value of immovable property that had to be paid annually. In Amsterdam, the citywide verponding registration started in 1647 and continued into the early 19^th century. With the introduction of the cadastre system in 1810, the verponding came to an end.

The original tax registration is kept in the Amsterdam City Archives (Archief nr. 5044) and the four registration books transcribed in this dataset are Archief 5044, inventory 255, 273, 281, 284. The verponding was collected by districts (wijken). The tax collectors documented their collecting route by writing down the street or street-section names as they proceed. For each property, the collector wrote down the names of the owner and, if applicable, the renter (after ‘per’), and the estimated rental value of the property (in guilders). Next to the rental value was the tax charged (in guilders and stuivers). Below the owner/renter names and rental value were the records of tax payments by year.

This dataset digitises four registration books of the verponding between 1647 and 1652 in two ways. First, it transcribes the rental value of all real estate properties listed in the registrations. The names of the owners/renters are transcribed only selectively, focusing on the properties that exceeded an annual rental value of 300 guilders. These transcriptions can be found in Verponding1647-1652.csv. For a detailed introduction to the data, see Verponding1647-1652_data_introduction.txt.

Second, it geo-references the registrations based on the street names and the reconstruction of tax collectors’ travel routes in the verponding. The tax records are then plotted on the historical map of Amsterdam using the first cadaster of 1832 as a reference. Since the geo-reference is based on the street or street sections, the location of each record/house may not be the exact location but rather a close proximation of the possible locations based on the street names and the sequence of the records on the same street or street section. Therefore, this geo-referenced verponding can be used to visualise the rental value distribution in Amsterdam between 1647 and 1652. The preview below shows an extrapolation of rental values in Amsterdam. And for the geo-referenced GIS files, see Verponding_wijken.shp.
