Generate a Precipitation Map, similar to:





**Acceptance Criteria**
- [ ] first
- [ ] second
- [ ] third

**Additional context**
- Liz C the forecaster has the R Script to generate this
- Forest Hydrology group is already using the script
- Data available via our [MSC GeoMet](https://can01.safelinks.protection.outlook.com/?url=https%3A%2F%2Feccc-msc.github.io%2Fopen-data%2Fmsc-data%2Fobs_radar%2Freadme_radar_geomet_en%2F&data=05%7C02%7Cbcws.predictiveservices%40gov.bc.ca%7Ca0b8444341514bf65e5f08dce877590b%7C6fdb52003d0d4a8ab036d3685e359adc%7C0%7C0%7C638640846521951234%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C&sdata=7NQDmk0qvqhkmO4PENooAUY06v42uJZiXg82Inu3idI%3D&reserved=0) geospatial web services and [MSC AniMet](https://can01.safelinks.protection.outlook.com/?url=https%3A%2F%2Feccc-msc.github.io%2Fmsc-animet%2F%3Flayers%3DRADAR_1KM_RRAI%253B0.75%253B0%253B1%253B0%253B1%2CRADAR_COVERAGE_RRAI.INV%253B0.75%253B0%253B1%253B0%253B1%2CRADAR_COVERAGE_RRAI%253B0.75%253B0%253B1%253B0%253B1%26extent%3D-18138165%2C1096488%2C-2441858%2C8260390&data=05%7C02%7Cbcws.predictiveservices%40gov.bc.ca%7Ca0b8444341514bf65e5f08dce877590b%7C6fdb52003d0d4a8ab036d3685e359adc%7C0%7C0%7C638640846521971768%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C&sdata=ZUbIxv3Dr4FhUOcrw3dQ3qCo5munvwwGK%2BbVpVh3q1E%3D&reserved=0), as well as the official ECCC [WeatherCan](https://can01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.canada.ca%2Fen%2Fenvironment-climate-change%2Fservices%2Fweather-general-tools-resources%2Fweathercan.html&data=05%7C02%7Cbcws.predictiveservices%40gov.bc.ca%7Ca0b8444341514bf65e5f08dce877590b%7C6fdb52003d0d4a8ab036d3685e359adc%7C0%7C0%7C638640846521991797%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C&sdata=LN25Zm%2F2usE262GYydjQyHKo4%2F47AVd58q0YpX0Md%2F8%3D&reserved=0) mobile app and the [https://weather.gc.ca](https://can01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fweather.gc.ca%2F&data=05%7C02%7Cbcws.predictiveservices%40gov.bc.ca%7Ca0b8444341514bf65e5f08dce877590b%7C6fdb52003d0d4a8ab036d3685e359adc%7C0%7C0%7C638640846522010840%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C&sdata=baKMmUqfJHRaqkHz9mR%2BZ%2BQSexZqRtyKwNi6Mfn1%2FUk%3D&reserved=0) website.

Start by obtaining and reviewing Liz C's R Script, then compare its output with the referenced precipitation-map examples and the MSC GeoMet, MSC AniMet, WeatherCan, and weather.gc.ca sources. Done means the project generates a precipitation map matching the agreed requirements; the current first, second, and third acceptance criteria need to be defined before implementation.
