Spatial analysis with guidance (internal)
Internal 3 credits GIS Spatial data Manipulations Layout SolutionAS 91247, 3 credits — the Level 2 GIS standard. Three components: collect spatial data relevant to the problem, complete manipulations to produce a layout, and explain an appropriate solution based on those manipulations, supported by evidence. The standard's own named manipulations (note 3) are simpler than full GIS vocabulary — know its actual closed list.
1 Reading the notation
The standard's own named manipulations are simpler than full GIS vocabulary — know its actual closed list.📖 Terms the schedule grades you on
5 terms- Apply spatial analysis (Achieved)
- Collect relevant data; complete manipulations for a layout; explain a solution based on them, with evidence.
- Effectively apply (Merit)
- SUFFICIENT data; ACCURATE layout; solution explained IN DETAIL.
- Comprehensively apply (Excellence)
- FULLY explain a VALID solution, supported by DETAILED evidence.
- Manipulations (note 3)
- Measuring, layering, changing symbols, sorting/editing a table, querying the map, coordinate systems, graphing.
- Geographic problem
- A real, located, spatial problem — cannot be a simulation.
2 A real, spatial, non-simulated problem
The "cannot be a simulation" clause rules out hypothetical scenarios. ✕Using advanced GIS terms not in the standard's own list
Terms like "buffer" and "overlay" are legitimate GIS operations and may still appear in your software, but the standard's own note 3 names measuring, layering, symbol changes, table sorting, querying, coordinate systems, and graphing. Grounding your write-up in the STANDARD'S OWN terms is the safer, more precisely evidenced choice.3 The named manipulations, and the layout
Layering and querying are the two workhorses — the standard's own equivalents of overlay and attribute query.| Manipulation (note 3 wording) | What it answers | Justify by stating |
|---|---|---|
| Layering | Where do multiple layers relate to each other? | Which layers are essential to the problem |
| Querying the map | Which features meet a value condition? | Why that threshold value |
| Measuring | How far, how big, how much? | Why that measurement matters to the problem |
| Classification / symbol change | Where is concentration highest? | Why those class breaks or symbols |
For each operation, write one sentence on what it did and one on why it was the right choice. Then the solution can cite them as evidence.
4 A solution based on the manipulations
Point at the layout, state the solution, cite the specific evidence.What the solution needs
- A direct citation of what the layout/manipulations show.
- The solution stated, following from that evidence.
- A named limitation of the spatial data.
- A non-spatial factor the analysis cannot capture, named.
Practice
Recall it first, then use it — testing yourself builds the memory, where rereading the notes above only feels easier.
Recall and application shuffled together — you have to work out what each item wants before you can answer it, which is the part the exam actually tests. Both kinds feed the same spacing schedule, so anything you miss comes back sooner.
Say the answer out loud before flipping — that attempt is where the learning happens, even when you get it wrong.
