Part 1: ESRI Training 1 - Getting Started with ArcGIS Pro ESRI Training 2 - Getting Started with Data Management

ESRI Training 3 – Introduction to coordinate systems Part 2: Q1: The two fields that best describe the location of each observation are latitude and longitude. The field that describes the reliability of that position is the positional accuracy column. Q2: Three reasons to use the common name field instead of the species guess field are that the common name field has all the names in the same language (English), it is not missing any entries (no null spaces), using the common name will allow more people to reference the data as they do not have to guess what the observer thought the animal was. Q3: a) The observation data is point data b) The provinces are polygon data c) The roads are line data Q4: There are 274 observations of humpback whales Q5: The attribute query used to answer Q4 was “select by attribute” utilizing common_name. Q6: The most recent Eastern American Red Fox observation was on 11/6/2021 Q7: The answer to Q6 was determined by using a “select by Attribute” query, selecting common_name by “eastern American red fox”, highlighting the selected attributes, then scrolling the attribute table until a highlighted row was found. Q8: There are 2 observations that occurred north of 49° latitude

Q9: The single attribute query that accomplishes Q8 is “ common_name = 'Eastern American Red Fox' And latitude > 49.00002176 ” Q10: Assuming a radius of 50km around each megacity location, 30185 animals are found “within” a population center. Therefore 1-(30185/109866) = 0.725 = 72.5% of observations occurred outside of a population center. Q11: Q10 was answered by using a select by attribute query to identify the mega cities, then using a select by location query to relate the found iNaturalist observations to the found megacities within an assumed radius of 50km. This produced a value of 30185 observations. Subtracting this from the total number of observations returns the number of observations located outside of a population center (79681).

Part 3: East-most whale: 47.516667, -52.633333 West-most whale: 54.149719, -132.644604 Q12:The distance between the two points is 5377.48 km Q13: The distance between the 2 sightings is 8983.56 km Q14: The distance is 5377.48 km Q15: The new distance is the same as the geodesic distance calculated in Q12 Q16: The new distance is less than the planar measurement found in Q13 Q17: The planar area of Manitoba is 1957031.05 km 2 Q18: The new area is 656698.00 km 2 Q19: Using the geodesic method the area of Manitoba is 641481.08 km 2 . The projection that comes closest to the geodesic method is the planar measurement using the world Mollweide projection. This is because the Mollweide projection considers the curvature of the earth whereas the Mercator projection fully flattens the globe.
