Geog 458: Map Sources and ErrorsQuiz for NSDI and CSDGMFebruary 6, 2006Your Name ________________________________This quiz is OPEN BOOK. You can look up the course packet as many as possible. I. NSDI and metadata 1. What is National Spatial Data Infrastructure (NSDI)?2. What are five core components of NSDI?3. What is National Geospatial Data Clearinghouse (NGDC)?4. {True, False} The intent of NGDC is to centralize all geographic data in one location.If your answer is false, correct the sentence.5. Why do you think metadata is important? Summarize your views with three or more sentences in plain English. II. CSDGM: Overview & Definition of Terms6. {True, False} Content Standards for Digital Geospatial Metadata (CSDGM) specifies the format of metadata for a set of digital geospatial data. If your answer is false, correct the sentence.7. What is the relationship between CSDGM and NGDC?18. Why do you think CSDGM is so complex AND structured? It is complex or detailed because _________________________________________It is structured because _____________________________________________9. What are the seven primary (major) sections of CSDGM?1)2)3)4)5)6)7)10. Among the seven primary sections of CSDGM, which sections are mandatory? What about remainders? Are they optional or not? You should check production rules of metadata to answer this question. 11. What are the three supporting (minor) sections of CSDGM?8)9)10)12. Can be the three supporting sections used alone? Why are they described separately inthe standard? 13. Draw a Ven Diagram for Sections, Compound Elements, and Data Elements used in CSDGM. In other words, what are their compositional relations? 2III. Where to look up in CSDGM?Let’s assume you have QA sessions for metadata novices. Answer their questions by saying “you should look up this part in CSDGM”. Pinpoint Data Elements hierarchically organized within CSDGM. Put section numbers followed by section > compound element(if any) > data element as shown below. Depending on questions, answers can be multipledata elements.Examples: Q. Who produced the data set?A. 8.1 Identification > Citation > Originator To make sure if your answer IS Data Element, look at the value after Type: in the corresponding subsections; if it’s not compound, it’s data element14. What geographic area (in precise coordinates) does the data set cover?A. 15. Is this a digital map or remote-sensing image, or something different like tabular data? In which style is the data presented?A. 16. To whom should I address questions about the data?A. 17. Why was the data set created?A.18. How was the data set created?A. 19. What can you say about the accuracy of the observations in attribute data?A. 20. If data vary in depth or height, how accurately is vertical position known?A. 21. Where are the gaps in the data? What is missing there?A.22. Who distributes the data?A.323. By what name does the distributor know this data set?A.24. What hardware or software do people need in order to use the data set?A.25. Who wrote the metadata?A.26. To what standard are the metadata intended to conform?A.Bonus questions (27-28)27. What geographic area (in known place name) does the data set cover? A. 28. I am not sure if the temporal information of the data set is determined by publication date or ground condition. Where should I look for in the metadata?A.IV. CSDGM: Details29. How is the section Spatial Reference organized? Draw tree-like structure of the section in 3 levels. 1 level corresponds to Sections of CSDGM (e.g. Identification). Do not include optional elements. If the elements in the same level is complementary (in other words, either element A or element B), use OR between the line.Example: Data quality in 2 levels 1 level 2 levels Attribute_AccuracyData_Quality Logical_Consistency_Report Completeness_Report Positional_Accuracy LineageSpatial_Reference430. How is the section Entity and Attribute organized? Draw tree-like structure of the section in 3 levels. What is the difference between Detailed Description and Overview Description in the section Entity and Attribute? What is the difference between Entity_Type and Attribute?31. Look at 1.5 Identification > Spatial Domain. Distinguish between 1.5.1 Bounding Coordinates and 1.5.2 Data Set G-Polygon by pinpointing them in the map below.32. Look at page 39 in FGDC-STD-001-1998. There are four kinds of domain values {Enumerated Range, Codeset, Unrepresentable}. Which of the following is NOT true?a) “road type” is the example of range domainb) “age” is the example of range domainc) “FIPS” is the example of codeset domaind) “people’s name” is the example of unrepresentable domain-- End of Quiz
