The City’s Geographic Information System (GIS) staff provides information about the City to its citizens and employees. We maintain accurate corporate limits, streets, zoning, and many other layers of information in our City’s GIS system.
We also provide technical assistance to other departments to help them develop and maintain their own GIS information. Our staff is currently working towards creating a system from which all City employees will have real time access to our GIS information.
The most common way that we communicate GIS information with residents and employees is through maps. We can produce maps up to 34″ x 44″ in size for a minimal fee. Citizens can request a map by emailing us at mckeet@ci.charleston.sc.us, calling or coming by our office at 75 Calhoun Street. Some of our most popular maps are available online for viewing and downloading.
A Geographic Information System (GIS) is a system of computer software, hardware and data, and personnel to help manipulate, analyze and present information that is tied to a spatial or geographic location. GIS is NOT a Global Positioning System (GPS) nor is it a static or paper map. Maps are a product of GIS. GIS is really a ’smart map’. Every feature, such as a street, parcel or building is actually linked to a database that contains information about that feature such as the street name, property owner, or building height.
GIS is so powerful because it allows us to view this information in map form instead of a complex database. Additionally, because features are associated with a geographic location they know how they are related to each other. For example, a GIS can tell you what property owners and therefore how many residents are within a 1 mile radius of a particular park.

Todayâs â55 Plusâ Communities or âRetirementâ Communities mean more than a collection of residences in the same neighborhood or geographic area. Communities set a yardstick for design and development and provide an impression of sureness your investment will be protected and preserved. It does not so much concern the community being âgatedâ as much as it concerns the fact that they are âplanned.â Whether you have a guard house or gate or not, inhabitants feel more protected living in a community with compatible individuals with similar interests and these are becoming very popular especially with retired individuals. Most all communities are deeded real estate. These days, there are many different sorts and modes of âcommunitiesâ which have different kinds of amenities. An âActive Adult Communityâ is an age-restricted community requiring that at the least one household resident is age 55. No teenagers or children can live permanently. Residents are normally occupied with community pursuits and are retired, occupied in some fashion, or run their own business. Many Adult Communities do the maintenance of the property for the residents. I choose to refer to them as Active Lifestyle Communities since, essentially, the spotlight these days seems to be more on lifestyle and conveniences, and not on age. Several communities concentrate on horses, boating, golf, fitness or some other outdoor activity. They have some dash to them. âPrivate Residence Clubsâ are deeded real estate ownership (fractional ownership) devoid of the added responsibility of owning. The cost changes with the dwelling and number of weeks in your plan. With âDestination Clubsâ you donât own any of the real estate and for only a membership fee and year on year charges, provide access to houses throughout the world. The 2 categories present premium accommodation at resort destinations… Continue reading

Solar Photo Voltaic Modules are best known as a method for generating electric power by using solar cells to convert energy from the sun into electricity. The Solar Photo Voltaic Module effect refers to photons of light knocking electrons into a higher state of energy to create electricity. The term photovoltaic denotes the unbiased operating mode of a photo-diode in which current through the device is entirely due to the transduced light energy. Virtually all photovoltaic devices are some type of photo-diode.Solar cells produce direct current electricity from light, which can be used to power equipment or to recharge a battery. The first practical application of photovoltaic was to power orbiting satellites and other spacecraft, but today the majority of photovoltaic modules are used for grid connected power generation. In this case an inverter is required to convert the DC to AC. There is a smaller market for off-grid power for remote dwellings, boats, recreational vehicles, electric cars, roadside emergency telephones, remote sensing, and cathodic protection of pipelines. Average solar irradiance, watts per square meter. Note that this is for a horizontal surface, whereas solar panels are normally mounted at an angle and receive more energy per unit area. The small black dots show the area of solar panels needed to generate all of the world’s energy using 8% efficient photovoltaic.Cells require protection from the environment and are usually packaged tightly behind a glass sheet. When more power is required than a single cell can deliver, cells are electrically connected together to form photovoltaic modules, or solar panels. A single module is enough to power an emergency telephone, but for a house or a power plant the modules must be arranged in multiples as arrays. Although the selling price of modules is still too high to compete with grid… Continue reading
