Slope stakes in road or canal construction are set out to mark:
सही उत्तर: क) The points where the side slopes of a cutting or embankment meet the natural ground
Slope stakes show the outer limits of earthwork, i.e. the toe of fill or top of cut.

In setting out the foundation trenches of a building by the centre line method:
सही उत्तर: घ) The centre lines of walls are marked first, and trench widths are set out on either side of them
Marking centre lines on profile boards allows the trench width to be set out equally on both sides.

If each of n observations of a quantity has unit weight, the weight of their arithmetic mean is:
सही उत्तर: ग) n
The weight of the mean of n equally weighted observations is n times the weight of a single observation.

The principle of least squares used in the adjustment of survey observations states that the most probable values are those for which:
सही उत्तर: ख) The sum of the squares of the residuals is a minimum
Least squares adjustment chooses values that minimise the (weighted) sum of squared residuals.

In surveying, 'accuracy' refers to:
सही उत्तर: क) The closeness of a measurement to the true value
Accuracy relates to the true value; precision relates to repeatability of measurements.

In GIS, 'metadata' means:
सही उत्तर: घ) Data describing a dataset, such as its source, date, accuracy and coordinate system
Metadata is 'data about data', helping users judge whether a dataset is suitable for their use.

Georeferencing a scanned map or image in GIS means:
सही उत्तर: ग) Assigning real-world coordinates to it using control points
Georeferencing links image positions to ground coordinates so that the data can be overlaid with other layers.

-
In GIS, an 'overlay' operation is used to:
सही उत्तर: ख) Combine two or more spatial layers to produce new information, e.g. land use within flood zones
Overlay intersects or unions layers so that their attributes are combined for analysis.

-
In the vector data model of GIS, geographic features are represented as:
सही उत्तर: क) Points, lines and polygons defined by coordinates
Vector data stores features as coordinate-based points, lines and polygons; raster data uses grid cells.

A 'pseudorange' measured by a GPS receiver is:
सही उत्तर: घ) The range computed from the signal travel time, which includes the effect of receiver clock error
Because the receiver clock is not perfect, the measured range contains a clock bias, hence 'pseudo'; it is solved as a fourth unknown.
