What are y axis values in Google Earth?
Y-axis values are the reduction of image pixels in a given region, grouped by day-of-year, for a selected image band. The following examples rely on an ImageCollection that is a time series of MODIS-based NDVI and EVI.
How are series defined in Google Earth Engine?
Series are defined by years present in the ImageCollection. Y-axis values are the reduction of image pixels in a given region, grouped by day-of-year, for a selected image band. Image day-of-year is plotted along the x-axis according to the system:time_start property. Series are defined by regions.
How to show day of year in Google Earth?
Use ui.Chart.image.doySeriesByYear to display a day-of-year time series for a given region and image band, where each distinct year in the image collection is presented as a unique series. It is useful for comparing annual time series among years.
How to create a time series in Google Earth?
Load MODIS imagery and calculate snow index. Dynamically select lat/longs for creating time series plots. Create a time series of NDSI for a selected point. This code allows users to dynamically generate time series plots for from points that are dynamically chosen on a map on the fly.
How to use Google Earth API in Python?
In this tutorial, an introduction to the Google Earth Engine Python API is presented. After some setup and some exploration of the Earth Engine Data Catalog, we’ll see how to handle geospatial datasets with pandas and make some plots with matplotlib. First, we’ll see how to get the timeseries of a variable for a region of interest.
How to create a Google Earth imagecollection chart?
Use ui.Chart.image.doySeriesByRegion to display a single image band day-of-year time series for multiple regions, where each distinct region is presented as a unique series. It is useful for comparing annual single-band time series among regions.
How are image dates determined in Google Earth?
Image date is plotted along the x-axis according to the system:time_start property. Series are defined by image bands. Y-axis values are the reduction of images, by date, for a single region. Image date is plotted along the x-axis according to the system:time_start property. Series are defined by regions.
