This chapter describes the wide array of HUD data users and discusses methods for gathering and disseminating these data, and for developing related tools to support decision making and spatial analysis. HUD DATA USERS HUD data are important to a broad spectrum of users.

Most of the GIS efforts in HUD's field offices do not go beyond point and thematic mapping, because of limited understanding of spatial analysis, comparative spatial statistics, and housing indicator development (Michael Martin, U.S. HUD Milwaukee field office, personal communication, 2002~.

Using HUD housing data, Resident Advisory Councils can go online and see what is going on in their community. Ideally, these HUD datasets would incorporate local knowledge from these groups within the framework of a larger dataset.

Individuals who have vouchers in these situations may find that they cannot secure a place to live. GIS could provide a framework for keeping track of trends in the private housing market including rental prices, and lead to the development of additional means to provide affordable housing in urban areas.

People want information about their neighborhood, such as the availability of homes to rent or buy, and the location of social services and transportation routes. More advanced HUD data users want this information in the form of spatially enabled data with accessible metadata to show, find, and explain interesting trends and patterns.

56 GIS FOR HOUSING AND U~ANDEVELOPMENT BOX 3.1 Continued In the 1990s, Congress required states along the Mexican border to set aside a portion of their HUD-allocated Community Development Block Grant (CDBG) funds to alleviate poverty and improve housing in the colonies.

· For users with limited financial or technical resources, HUD should provide web-based mapping of HUD data and related information. · For more advanced applications, HUD should develop tools for flexible querying, extracting and downloading data, including standard file formats for exchanging data.

Online data tools that support a broad range of users will promote the use of geographic data. Research Clearinghouse HUD can build relationships with research communities to facilitate use of spatially enabled data to examine housing and urban issues.

From page 60... ...
These include better documentation, support for user conferences and online data user groups, a HUD USER newsletter focused on spatial analysis, and training to develop spatial analytical capabilities both in-house and for local data users. HUD could use the research clearinghouse to encourage researchers to examine urban and housing issues at different geographic scales and work closely with communities to develop research questions and create research products that are useable by communities, non-profits, and other local groups.
|
From page 61... ...
Many of the institutions, groups, and individuals who should be part of discussions about housing and urban issues lack access to technology and training to fully utilize GIS. Community organizations, neighborhood residents, and even HUD field of lice staff require both technical training and products that are easy to access and use.

Rather that log on to a web site, community users work closely with the expert staff of the center to identify research questions, negotiate partnerships to share data, develop maps to present the data, and build capacity to use the data and maps to influence public policy and address urban problems and issues. The Role of PD&R in Data Dissemination As outlined earlier in this chapter, PD&R plays an active role in the interagency work that HUD is doing in the colonies, in relationships with other HUD clients and partners (such as urban researchers and community groups)

· Support the functions of an agency-wide enterprise GIS across all relevant HUD units. HUD GIS SUPPORT TOOLS GIS Applications and Needed Technological Support HUD's mission has a strong spatial component so there is tremendous potential and need for spatially referenced data and geographic analysis for policy development.

From page 64... ...
GIS technology encompasses three integrated components at different levels of technological sophistication: database management technology, spatial analysis technology, and visualization technology. Database management technology is needed to store, retrieve, and convert large volumes of geospatial data.

The Clean Air Act Amendments of 1991, and ISTEA and TEA219 designate Metropolitan Planning Organizations as the principal agents in developing coordinated regional transportation plans, and require coordination of land National Bureau of Economic Research Harvard Urban Development Simulation (NBER MUDS)

This allows users to view only a few variables at a time, but does not promote the application of spatial data to complex urban and community issues. While capability varies among users, the development of spatial analytical ability is important for both professional researchers andfor local data users.
|
From page 68... ...
HUD uses a variety of tools to disseminate and promote the analysis of these data. More progress is required in building relationships for collecting data, disseminating spatial information and knowhow to HUD's clients, and devolving spatial analytical capabilities to .
