Household surveys and spatial data show that between20%and47%47% of rural people live within 2km of an all-season road.
Its budget in 2004-05 was roughly R69m, or £6m, though other work such as land title surveys and spatial planning amounted to R97m (£8.4m).
spatial units (parcels, and the legal space of buildings and utility networks) with the subpackage: spatial sources (surveying), and spatial representations (geometry and topology).
This paper presents the model framework TerraCE (Terrace Condition Erosion) for determining the causes for different terrace conditions and terrace degradation based on field surveys and spatial data mining.
The packages in LADM relate to: parties (people and organizations) basic administrative units, rights, responsibilities and restrictions (ownership rights) spatial units (parcels, and the legal space of buildings and utility networks) with the subpackage: spatial sources (surveying), and spatial representations (geometry and topology).
Sidescan sonar images from detailed benthic mapping suggest that although squids prefer a sandy substrate as their primary egg mop habitat, the depths across which egg mops were distributed differed significantly between surveys and spatial distribution of egg mops varied across years on this large spawning ground.
The very large changes in estimated abundance between years, and also between snapshots within a year, are related mainly to changes in survey temporal and spatial coverage, and illustrate an important limitation on interpretation of aggregation-based acoustic abundance estimates.
We used computer simulations to compare population estimates based on DO and DS methods for a range of detection probabilities, survey proportions, and spatial distributions.
These will include quantitative analysis of secondary data, surveys of facilities, questionnaires to mothers, community based surveys of households, and spatial analyses to study access.
Further, the sensitivity of the estimators to variations in detection probability, proportion of area surveyed, and the spatial distribution of the population within the survey area can be experimentally evaluated.
