Map Scale and Distance Calculations: Practical Examples
Map Scale and Distance Calculations
On a map with a scale of 1:200,000, the distance between two points is 87 mm. Calculate the actual distance on the ground:
1 mm —-> 200,000 mm
87 mm —-> x
x = 87 * 200,000 = 17,400,000 mm = 17.4 km
Expressed as a fraction, a 5 cm scale is equivalent to 20 km:
5 cm —-> 20 km
5 cm —-> 2,000,000 cm
1 cm —-> 400,000 cm. Therefore, the RSL (Representative Scale) is 1:400,000
Expressed as a fraction of English units, one inch on the scale equals

Time Series Analysis, Forecasting & Operations Management Concepts
Time Series Components
A time series is a set of values of a variable measured at successive points in time.
Key Components
- Trend: The gradual increase or decrease of a time series over a longer period.
- Seasonality: Regular patterns of variability within certain time periods, such as a year, week, etc.
- Cycle: Any regular pattern above and below the trend line lasting more than one year.
- Random Variations: Fluctuations caused by chance events and/or unusual situations.
