Web Mapping and GIS Final Exam
UPDATED ACTUAL Exam Questions and
CORRECT Answers
concept of standards and their use both outside of and for the geospatial industry
Why have them?
Be able to explain why important for web mapping and GIS - CORRECT ANSWER✔✔-
Standards makes things more efficient and effective by establishing norms
19500 standards
International Standards Organization
Goals of standards is to communicate, execute programs, or transfer data with user having
little or no knowledge
Software engineered to work with different formats
major standards organization for the geospatial industry and how it is comprised - CORRECT
ANSWER✔✔- Open Geospatial Consortium
Data, systems, and process standards
Specific standards for many industries (aviation, energy, sensor webs)
specific geospatial standards - CORRECT ANSWER✔✔- Geo(JSON) (Javascript Object
Notation)- lightweight data interchange format
KML (Keyhole Markup Language)-points,rasters,lines,polygons, defines visualizations
WMS (Web Map Service)-standard for requesting and serving georeferenced map images
over internet..how HTTP requests and responses are handled between client/server. rendered
on the fly,
WMTS (Web Map Tile Service)-predefined image files
WFS (Web Feature Service)-standard for reading/writing vector geographic data
WCS (Web Coverage Service)-retrieval of actual geospatial data
GML (Geography Markup Language)- exchange standard, modeling language for geographic
systems
GPX (GS eXchange Format)- stores GPS data
, XML (eXtensible Markup Language)-standard for exchanging and storing data/documents
there are data formats that are widely used but not necessarily adopted by standards
organizations - CORRECT ANSWER✔✔- their specifications are published and open so
software can be built to use them
WMS and WFS - CORRECT ANSWER✔✔- Web Mapping Service and Web Feature
Service
WMS-standard for requesting and serving georeferenced map images over internet..how
HTTP requests and responses are handled between client/server. rendered on the fly,
WFS-standard for reading/writing vector geographic data
contrast WMS with WMTS - CORRECT ANSWER✔✔- Web Mapping Service- around
longer, more flexible for returning custom georeferenced map images, clunky with potential
for slower responses
Web Map Tile Service-standard for delivering tiles, potentially reduces data and thus
bandwidth...more efficient
how WMS can be consumed by web mapping APIs and cloud-based web GIS - CORRECT
ANSWER✔✔- Web Mapping applications can access WMS, sending requests for images
(not tiles) that are rendered on the fly. when user zooms in a new image is requested.
How text files can be used in some software (e.g. cloud-based - e.g. CartoDB, Google My
Maps, etc.) - CORRECT ANSWER✔✔- Tabular data like CSV, Excel, Google Fusion Tables
can be used. what they can do and how they are used varies.
How we utilized data based on at least two of these standards in labs 4 and 6 - CORRECT
ANSWER✔✔- GeoJSON with Leaflet API to look at iowa counties poverty
CSV with CartoDB to look at twitter posts and animate them.
What is Cloud Computing - CORRECT ANSWER✔✔- computer paradign for enabling on-
demand network access to shared pool of configurable computing resources that can be
rapidly provided and released with minimal management effort or service provider interaction
Software on computers elsewhere (not personal computers)
