We provide a general framework to study convergence properties of families of maps. For manifolds $M$ and $N$ where $M$ is equipped with a volume form $\mathcal{V}$ we consider families of maps in the collection $\{(\phi, B) : B \subset M, \phi:B \rightarrow N\text{ with both measurable}\}$ and we define a distance function $\mathcal{D}$ similar to the $L^1$ distance on such a collection. The definition of $\mathcal{D}$ depends on several parameters, but we show that the properties and topology of the metric space do not depend on these choices. In particular we show that the metric space is always complete. After exploring the properties of $\mathcal{D}$ we shift our focus to exploring the convergence properties of families of such maps.
