Gathering data to inform your project is dependent on its scale, scope, and context. Common sources include site surveys and maps that provide information about the location, size, shape, topography, orientation, boundaries, and existing features. Soil and hydrology tests reveal characteristics and conditions of the soil and water on the site. Climate and microclimate data show patterns of temperature, precipitation, humidity, wind, solar radiation, and air quality. Vegetation and wildlife surveys identify types of plants and animals on the site as well as their ecological roles. Lastly, cultural and historical data indicate human influences on the site such as land use, ownership, zoning, regulations, heritage, traditions, aesthetics, and preferences. You can use various tools or methods such as GPS systems, GIS systems, drones or laser scanners to collect accurate data; laboratory or field methods for soil and water tests; weather stations or online databases for climate data; field observation or remote sensing for vegetation surveys; interviews or documents for cultural information; or visit the site for a more detailed assessment.
