A place is a network before it is a plan

This is the first map on the lineage map engine with no music on it. The Japanese Metal Family Tree and the Tampa death metal map are The Music Cities™ content; the Creator Economy Map and the West Dixie Music Corridor map are the crossover between The Music Cities™ and Street Economics®. This one is Street Economics® only. It exists to show that the same engine works for pure economic development: a place and its economy mapped as a network and a lineage, and it gives Street Economics® Detection #3, South Dade, an evidence layer that the detection page links to.

Every node is a place, a project, a station, a road, an event, a person or family with a documented role, or an institution: an employer, an agency, a developer, a plan, a program. Nodes belong to one of ten layers of the place, not eras: towns and districts, people and population, employment anchors, transit and roads, agriculture and the Redland, parks, water and recreation, gathering places and culture, plans and agencies, development and capital, and the digital layer. A rose ring marks a documented gathering place (58 on the map). An orange dotted ring marks something Hurricane Andrew wrecked that was rebuilt or replaced (23). The 15 community hubs, the four municipalities and the census designated places, are both nodes in the towns layer and the anchors of the Cities view.

Connections come in three weights. Solid lines are the moves that carry know how and capital: a developer active on a named project, a person or firm moving between two nodes, a plan or business spawning another, a founder, a predecessor becoming a successor (198 on the map). Dashed lines are influence, used only where a source says one thing shaped another (50). Dotted lines are plans, funding, anchoring, stations and roads connecting places, partnerships and hosting (273). A fourth, fainter class ties every node to the community it sits in (290); it is off by default on the interactive map and excluded from the centrality calculation, because every node is located somewhere by construction.

What a lineage means here. On the music maps the lineage is people moving between bands. Here it is how a place is made: the railroad arriving, the towns incorporating, the base, the speedway, the storm, the busway, the CRAs, the plans, the projects, the developers who move from one project to the next, the employers that anchor a district, the families and institutions that have been there for generations, and the newcomers. Trace lineage on the interactive map follows the solid lines upstream and downstream.

Inclusion rules. A node is on the map when it carries a founding, opening, incorporation or occurrence year with a source and at least one documented link to another node. A developer or firm is on the map only with a documented role on a named project; residence alone is never enough. Projects are worded as approved, under construction, delivered or announced from the filing that says so, never as built until a public record says built. Superlatives are qualified: within this dataset, in the project’s reading. The owner’s BusinessFlare® client work in South Dade stays out of this reference product; only public documents are used, including public CRA plans cited as public documents.

Timeline placement. On the lineage view and in the Play animation a place, institution, project or event enters at its founding, opening, incorporation or occurrence year and a person or family at their first documented act, taken from the earliest dated relation on the map. A node with no recorded year enters at the first year the map documents it and never earlier; the interactive panel labels these under Placed at, and the Nodes sheet carries the basis in its Place year basis column. A node with no dated link at all enters at the cutoff year. Influence relations never date a node.

Geography. The Cities view uses a basemap cut from Miami-Dade County open data: municipal boundaries for Homestead, Florida City, Cutler Bay and Palmetto Bay, the 2010 census designated places, the South Dade Transitway from the SMART Plan corridor layer, the county bus stop points on the corridor, US 1, Krome Avenue, the Turnpike extension, Palm Drive, Campbell Drive and Old Cutler Road from the major roads layer, the two national parks and the coastal municipal boundary for the shoreline. Every node is pinned at its address or centroid; a node with no address sits at its community’s centroid and says so. Nodes that span the whole corridor sit in Biscayne Bay and outside actors further out, so neither is mistaken for a place. The countywide context stays off the map; South Dade is the whole frame.

What the map shows. South Dade has many documented destinations and one major historic gathering cluster in downtown Homestead. The mapped pattern is dispersed: 58 documented gathering places, 20 within 600 metres of a Transitway station, 2 clusters of three or more, and 24 standing alone. The map documents fragmentation and uneven concentration; the detection's argument about belonging remains an interpretation of that pattern.

Community hubs. Community hubs are map geography, not incorporated status. They include four municipalities, census designated places, historical or unincorporated communities (Perrine and the Redland), the corridor wide South Dade hub, and Outside South Dade. A node is assigned to the hub containing its address or, where no address is available, the documented community or a stated centroid. The Nodes sheet carries the hub type of every node.

Network interpretation. Node size on the map and the centrality figures in this document are computed on this dataset with every edge type weighted equally and parallel edges counted separately, community hubs and located links excluded. They describe position in the map, not size, budget or importance; an employer with one anchoring link is small however many people it employs. A ranked table and the counting method are in the Network metrics section.
