Topography and Water Utilities Geospatial Mapping

These flashcards cover key concepts related to geospatial mapping, the assessment process, and essential utilities like stormwater, sewer, and water reticulation systems.

What is the primary aim of geospatial mapping?

To show items with geographic coordinates in a geographical framework, providing a representation of the physical world on a map.

What types of maps does Brisbane City Council’s online Geospatial Mapping service provide?

Maps for community and recreation, land and environment, transport, and utilities.

What is the purpose of the slope arrows in the topography analysis?

To illustrate the fall of the land surface across the study area.

What significant instances of topographic features should be annotated in the PDF documents?

High points (H), low points (L), ridge lines (R), trough lines (T), slopes (S), cliffs (C), embankments (E), walls (W), building edges with sharp elevation changes (B), level open spaces (O), and other significant features (F).

What components are included in the stormwater system?

Gully pit, surface drain, pipe end outlet, pipes, and culvert.

What is the significance of the sewer system being a gravity system?

It relies on gravitational force to move sewage from properties to treatment facilities.

What elements are part of the water reticulation system?

Scour valve, air valve, gate valve, end cap, reducer, tee, pressure gauge, flow meter, inground hydrant, trunk main, and reticulation main.

What is the standard water pressure in urban Brisbane?

21 meters of head, which equals 206 kPa.
