    This set of punctual data shows the manholes located on the Island of Montreal. These manholes are compartments through which sewers can be accessed in order to clean, inspect and maintain them. The manholes are placed at regular intervals on the right-hand section of the main pipe. In straight sections, the maximum distance between two manholes is 120 meters. The manholes are generally placed at the beginning of a network, i.e. at the head of the furthest section and at the points where the pipe changes direction, altitude, slope and/or diameter. The information associated with the geographic data corresponds to the type and material of the manhole, date of installation, status, owner and jurisdiction. __CAUTION__: This data is published annually, so it does not include updates made during the year. For this reason, they should under no circumstances be used for engineering purposes without validation by the City. **This third party metadata element was translated using an automated translation tool (Amazon Translate).**

    Each pixel value corresponds to the best quality maximum NDVI recorded within that pixel over the week specified. Poor quality pixel observations are removed from this product. Observations whose quality is degraded by snow cover, shadow, cloud, aerosols, and/or low sensor zenith angles are removed (and are assigned a value of “missing data”). In addition, negative Max-NDVI values, occurring where R reflectance > NIR reflectance, are considered non-vegetated and assigned a value of 0. This results in a Max-NDVI product that should (mostly) contain vegetation-covered pixels. Max-NDVI values are considered high quality and span a biomass gradient ranging from 0 (no/low biomass) to 1 (high biomass).

    Each pixel value corresponds to the actual number (count) of valid Best-quality Max-NDVI values used to calculate the mean weekly values for that pixel. Since 2020, the maximum number of possible observations used to create the Mean Best-Quality Max-NDVI for the 2000-2014 period is n=20. However, because data quality varies both temporally and geographically (e.g. cloud cover and snow cover in spring; cloud near large water bodies all year), the actual number (count) of observations used to create baselines can vary significantly for any given week and year.
