Last Exam Part 1 Study Guide

FINAL VERSION

In many countries in Europe the "electronic cadaster" is a reality. In this situation the electronic representation of a parcel is also the "legal" one. This is not the case in the US. Why do you think this is true?

What technical requirements must a GIS or other gepospatial data system have in order for it to serve as an electronic cadaster or/conversely what common operational characteristics of current GIS have that restrict their use in the cadaster?

Epsetin describes a number of different "interests" or "rights" associated with land ownership. Describe at least four different interests besides fee or fee simple and discuss how they present various issues for their representation in a GIS database.

What types of problems do easements present in the implementation of a GIS that deals with land records information?

Define the various "levels" of Census geography that are based on blocks .. which ones are limited to being contained within a signal county – which can overlap into two or more counties?

What column(s) in the Census data structure is used to isolate the specific data records applicable to a tract to county or MSA etc?

Based on the diagrams in the TIGER documentation (page 1-9) label ALL the elements in a similar (unlabeled) drawing

What is the BASIC content in the TIGER records Type 1, Type 2, Type 7, Type A, Type C, Type I and Type P?

If you were planning on geocoding general addresses accurately what two TIGER record types would be required?

If you were planning on creating a map showing three tracts (number X, Y and Z) describe how you would use EITHER TYPE 1 and TYPE 2 records alone or OR TYPE ! TYPE 2, TYPE I and P?

How can you separate the parts of a tract’s or block’s FIPS code (e.g. 05143210101) to identify the various larger geographies of which it is a part?

What is the basic difference between the types of attribute data found in a STF 1 versus an STF 3 data set. Which can be applied down to blocks and which down to tract?

What is a block numbering area and how does it compare to a tract?

What is a CFCC? How would you use it to create a map of all the (a) interstate exchanges (b) all underpasses (c) secondary roads (d) 4WD roads (e) railroad tunnel (f) power transmission line (g) apartment buildings (h) trailer court (I) jails or detention centers

Which parts of the Type 1 record are used to assign address values to the intersections and describe how geocoding software assigns a geographic coordinate to addresses between the intersections.

Some have said that the TIGER data structure is the "purest" form of the geo-relational data model. Discuss.

 Briefly describe how you would use the FGDC clearinghouse system to locate land use data for Montana.

How does the "bounding box" aspect of a metadata record provide you with information on where data is present? How can it be misleading?

Generally what would you define as the strengths and weaknesses of the FGDC geospatial metadata and clearing house approaches? What steps (if any) would you change/add/delete to make the system "better?"

What are the two "required" categories of CSDGM metadata? What are the "required if applicable" categories cover? Is there anything you think that is not required that should be?

Using the Wisconsins source list three software packages that are used to create FGDC metadata when the data is (a) from Arc Info sources on UNIX (b) any data on a Windows system and (c) only requires access to a web browser.

What are the key issues associated with data set versus feature metadata? Which approach do you think is appropriate and why? (Note see http://badger.state.wi.us/agencies/wlib/sco/metatool/mp.htm section 6.4)
