In USFWS/AKaerial: Analysis of Alaska Region Aerial Survey Data

Display multiple years of observation data by survey area

Description

ShowMeYears will take input data for an area and range of years and display them using Leaflet.

Usage

ShowMeYears(area, year, species = "all")

Details

ShowMeYears is designed to take a combination of area and year(s) and look up associated files in the MasterFileList to display the exact stratification and data that would be used to generate index estimates using an interactive Leaflet map. Data can be filtered to a single species or group of species. Clicking on strata will bring up the STRATNAME field associated with the click. Clicking an observation will display the observer initials, species code, observation type, number of the type observed, transect number reported by the pilot or observer., and year of the observation.
